Helppppp plzzzzzzz!!!!!!! 20+PTS and brainliest!!!!!!!!!

Transformations to the absolute value parent function are described. Write the new function.

13. Translated 9 units right.
14. Reflected in the x- axis.
15. Vertically compressed by a factor of 3/4.
16. Shifted 4 units up.

Respuesta :

Translated 9 units right.

g(x)=|x-9|

 Reflected in the x- axis.

g(x)=-|x|

 Vertically compressed by a factor of 3/4.

[tex]g(x)=\frac{3}{4}|x|[/tex]

 Shifted 4 units up.

g(x)=|x|+4

Given

Absolute parent function that is f(x)=|x|

Translation up:

For translation right by 'k' units

f(x) becomes f(x-k)

Translated 9 units right , the new function

[tex]g(x)=f(x-9)=|x-9|\\g(x)=|x-9|[/tex]

Reflect in x axis

f(x)=-f(x)

[tex]g(x)=-|x|[/tex]

Vertically compressed by 'k' factor

f(x) becomes k times f(x)

Vertically compressed by a factor of 3/4.

[tex]g(x)=\frac{3}{4} |x|[/tex]

Shifting up by 'k' units

f(x) becomes f(x) +k

Shift 4 units up

[tex]g(x)=|x|+4[/tex]
