Answers
Answer:

Step-by-step explanation:
y
y=ax
where a is a constant of proportionality;
y=20, x=4
20=4a
a=20/4
a=5
y=5x
The constant of variation is 5
The constant of variation for the given relationship is 5.
What is Direct Variation?Direct variations are defined as the functions of the form y = kx, where k is a constant.
Here when y increases, x increases and if y decreases, x also decreases.
Given that,
y varies directly as x
So the equation will be of the form,
y = kx
Here k is the constant of variation.
Given, y is 20 when x is 4.
So, 20 = 4k
k = 20 / 4 = 5
Hence the constant of variation for the given relationship is 5.

Find a function, g(x) that transform f (x) = 3 sqrt x by shifting f (x) right 3 units
Answers
Given
The function is
[tex]f(x)=3\sqrt{x}[/tex]
The function g(x) transform by shifting f(x) right 3 units.
To find:
The function g(x).
Step-by-step explanation:
The translation is defined as
[tex]g(x)=f(x+a)+b[/tex]
where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The function f(x) shifts only 3 units right. So,
[tex]a=-3,b=0[/tex]
Now,
[tex]g(x)=f(x+(-3))+0[/tex]
[tex]g(x)=f(x-3)[/tex]
[tex]g(x)=3\sqrt{x-3}[/tex] [tex][\because f(x)=3\sqrt{x}][/tex]
Therefore, the required function is [tex]g(x)=3\sqrt{x-3}[/tex].
