which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4?
a - q(x)=(1/4 x)^7
b - r(x)=(4x)^7
c - s(x)=4x^7
d - t(x)=1/4 x^7

i think it’s B; please check my answer

Respuesta :

The function given to us is : [tex]f(x) = {(x)^7}[/tex]

We want to see which function represents the horizontal compression of f(x) by a factor of 4

We can compress a function horizontally by multiplying the x by a constant number, in this case multiplying x by 4

So horizontal compression of [tex] f(x) = {(4*x)^7}[/tex]

This matches with the option B = [tex] r (x) = {(4*x)^7}[/tex]

Hence, your answer (B) is correct.

B is the correct answer. If you're doing the quickcheck its CACB
