ANSWER

Only the equation is a function

Step-by-step explanation


f(x)=x^2+8 is graphed above with its inverse
f^(-1)(x)=\pm √(x-8).


We perform the vertical line test for both the equation and its inverse.


The equation
f(x)=x^2+8 passed the vertical line hence it is a function.

However,
f^(-1)(x)=\pm √(x-8) failed the vertical line test, hence it is not a function.
