For the function f(x)=(7-8x)^2, find f^-1. Determine whether f^-1 is a

it's clear that the inverse is not a function, since there are a positive and negative value for x that give the same value for y.

y = (7-8x)^2
±y = 7-8x
8x = 7±y
x = (7±y)/8

thanks

B t is inverse not
A
A
A
C 4

For Honors it is
B- Relation t is a function. The inverse of relation t is a function.
A- y=squared x+3 divided by 7
B- The graph with one on the bottom and one on the left side
A- 7 plus minus sign squared x divided by 8. f^-1 is not a function
C- 4

i luv u 🥲

... is 100%
