Answer:
Im not sure but i think 2 is the answer
Step-by-step explanation:
If the function f(x) = x2 has the domain {0, 1, 4, 9), what is its range?
1.
{0, 1, 2, 3}
2.
{0, 1, 16, 81)
3.
{0, -1, 1, -2, 2, -3,3}
4.
{0, -1, 1, -16, 16, -81, 81}
so the right answer is {0,1,16,81}
Look at the attached picture
Hope it will help you
Good luck on your assignment..
The Range of function is, {0, 1, 16, 81}
Option 2 is correct.
The input values to any function is known as domain and output values of function known as range of function.
Given function is, [tex]f(x)=x^{2}[/tex]
Domain is, {0, 1, 4, 9}
Range of function is,
[tex]f(0)=0^{2}=0\\\\f(1)=1^{2}=1\\\\f(4)=4^{2}=16\\\\f(9)=9^{2}=81[/tex]
Thus, Range of function is, {0, 1, 16, 81}

Gianna used two refrigerators, each set to a different temperature, to cool two cups of hot liquid.
She placed the first cup in refrigerator A. The temperature, in degrees Fahrenheit, of the liquid in this cup, after x minutes in the refrigerator, is represented by the graphed function.
She placed the second cup in refrigerator B. The temperature, in degrees Fahrenheit, of the liquid in this cup is represented by an exponential function that has a y-intercept of 96 and approaches 38 as x increases.
When Gianna initially placed two cups in the refrigerators, the liquid placed in refrigerator A was ____ than the liquid placed in refrigerator B. The ____ of the two functions implies that refrigerator A is set to a ____temperature than refrigerator B.
1a. Cooler
1b. Warmer
2a. Y-intercepts
2b. End behavior
3a. Lower
3b. Higher
The answers are
1). warmer
2). end behavior
3). higher
When Gianna initially placed the two cups in the refrigerators, the liquid placed in refrigerator A was warmer than the liquid placed in refrigerator B.
The end behavior of the two functions implies that refrigerator A is set to a
higher temperature than refrigerator B.

Using sine and cosine, explain how you know where the graph of tangent will
have vertical asymptotes and x-intercepts.
Remember how the tangent function is defined as
[tex]\frac{sinx}{cosx}[/tex]
Now where exactly are the vertical assymptotes? Well, where cosx = 0, because anything over 0 is undefined, and where a value is undefined, you are required to draw a vertical assymptote.
Now where exactly are the x interecepts? Well, where sinx = 0, because remember, an x-intercept is where y = 0, or where it crosses the x-axis, meaning where the tangent function is equal to 0.
So the x-intercepts are at where sinx = 0.
Graph of the tangent will have vertical asymptotes when cosine function is 0 and has x intercept when sine function is 0.
What is Tangent function?Tangent function of an angle in a right angled triangle is defined as the ratio of the opposite side to the adjacent side.
Tangent function can be defined as,
f(x) = tan (x) = [tex]\frac{sin(x)}{cos (x)}[/tex]
Vertical asymptote of a function is the line x = m, where the graph of the function will move to infinity when x approaches m.
Here the function is tan (x).
tan (x) → ∞, when [tex]\frac{sin(x)}{cos (x)}[/tex] → ∞
[tex]\frac{sin(x)}{cos (x)}[/tex] → ∞, when cos (x) = 0, then x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], .......
Vertical asymptotes will be line through x = ±[tex]\frac{\pi }{2}[/tex], ±[tex]\frac{3\pi }{2}[/tex], ±[tex]\frac{5\pi }{2}[/tex], .....
x intercept is the point, where the y value equals 0.
That is, tan (x) = 0, at the point of x intercept.
[tex]\frac{sin(x)}{cos (x)}[/tex] = 0
⇒ sin (x) = 0
⇒ x = 0, π, 2π, .....
So tan(x) will have the x intercepts at x = 0, π, 2π, .....
Hence the vertical asymptotes and x intercepts of tan function can be found using sine and cosine.

Curious Carl calculated the density of a cube to be 4.50 g/cm3. What is the density of the cube in g/L?
A) 4.50 g/L
B) 45.0 g/L
C) 4500 g/L
D) 45000 g/L
Answer:
C) 4500 g/L
Step-by-step explanation:
1 L = 1000 cubic centimetres (cm³)
1 cm³ = [tex] \frac{1}{1000} [/tex] L
Density of cube = 4.50 g/cm³
= 4.50 × [tex]\frac{1}{\frac{1}{1000}}[/tex] g/L
= 4.50 × 1000 g/L
= 4500 g/L

Answer:
B. 16
Step-by-step explanation:
You need to work on the equation backwards. You know the answer, but you don’t know x. first, you divide 1536 by 6. you will get 256. next, you find the square root of 256. the square root of 256 is 16, so the answer is 16 :)
What is the amplitude and midline?
Answer:
The horizontal middle line in which the process oscillates above and below is a medium line of a sinusoidal system. The midline is y = 0 for y = sin x (x-axis). There was a misunderstanding. Amplitude is the oscillation magnitude (height) of the sinusoidal function (Wave).

Given: m∠A = m∠C = 90° AB ║ DC Prove: ∆ABD ≅ ∆CBD
Answer:
Angle-Angle-Side (AAS)
Step-by-step explanation:
Given triangles; ΔABD and ΔCBD
<A = <C = [tex]90^{0}[/tex] (right angle property)
AB ║ DC (given)
Then,
DA ║ CB
<B ≅ <D (congruent property)
DB ≅ BD (similarity property)
<D + <B = <B + <D (complementary angles, and property of triangles)
Therefore by Angle-Angle-Side (AAS),
∆ABD ≅ ∆CBD
