Domain and range of a graph please helppppp
Answer:
Domain : (-∞,∞)
Range : (-∞,∞)
Step-by-step explanation:
Domain is how many x-values the graph touches and Range is how many y-values the graph touches. And this graph has no point on which it stops nor any asymptotes, so both domain and range are all real numbers.

si un submarino esta a - 83 metros a nivel del mar, sube a -15 cuantos metros subio?
Answer:
El submarino subió 68 metros
Step-by-step explanation:
Desplazamiento
Si un cuerpo cambia de posición desde X1 hasta X2, su cambio de posición se calcula como:
X=X2-X1
En el caso de nuestro submarino, su posición original era a X1=-83 m, luego sube a la posición X2=-15 m, así que su cambio de posición o desplazamiento es:
X=-15-(-83)=-15+83=68 m
El submarino subió 68 metros

What is the remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2?
A. -23
B. 23
C. -3
D. 3
By the remainder theorem, dividing [tex]f(x)[/tex] by [tex]x-2[/tex] leaves a remainder of [tex]f(2)[/tex], which is
[tex]f(2)=2(2)^4+(2)^3-8(2)-1=\boxed{23}[/tex]
which makes B the correct answer.
The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
Polynomial based on degree is linear, quadratic, cubic.
The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial x - a, the remainder of is to f(a)
Given that f(x) = 2x⁴ + x³ - 8x - 1 is divided by x - 2
x - 2 = 0
x = 2
f(2) = 2(2)⁴ + (2)³ - 8(2) - 1 = 23
Hence The remainder when f(x) = 2x^4 + x^3- 8x - 1 is divided by x - 2 is 23

Since the image was created by reflecting across the x-axis,
that means that the original triangle was in the fourth quadrant
the image however is in the first quadrant
the coordinates of something in the fourth quadrant is (x, -y)
the coordinates of something in the first quadrant is (x, y)
so the answer is "c" since (x, -(y)) = (x, -y)

Step-by-step explanation:
Consider matrix A.
What matrix results from the elementary row operations represented by −2R2+3R1?
Answer:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]
Step-by-step explanation:
Given the matrix
[tex]A = \left[\begin{array}{ccc}-3&3&2\\8&-1&3\end{array}\right] \\R1 = -3, 5, 2\\R2 = 8, -1, 3\\\\[/tex]
Before we can get the resulting matrix after the elementary operation, we need to get the new second row using the formula −2R2+3R1?
when R1= -3, R2 = 8
−2R2+3R1? = −2(8)+3(-3)
−2(8)+3(-3) = -16-9
−2(8)+3(-3) = -25
R1= 5, R2 = -1
−2R2+3R1? = −2(-1)+3(5)
−2(-1)+3(5) = 2-15
−2(-1)+3(5) = -13
when R1= 2, R2 = 3
−2R2+3R1? = −2(3)+3(2)
−2(3)+3(2) = -6-6
−2(3)+3(2) = 0
Hence the new R2 are -25, -13, 0
The resulting matrix will be:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]
