Which function is a horizontal compression of its parent function f(x)=x^7 by a factor of 4 o q(x)=(1/4)x^7 o r(x)=(4x)^7 o s(x)=4x^7 o t(x)=1/4 x^7

we are given

Horizontal Compression:

Suppose, we want to compress a function f(x) horizontally by 'a' units

so, we can replace x as ax

f(x)---->f(ax)

Here, it is compressed horizontally by 4 units

so, we can replace x as 4x

so, we get

so,

.............Answer

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

x/3-10=8

x/3=18

x=48
