The functions f and h are defined as follows:

f(x) = (x + 5)/(x - 7)  and h(x) = (x + 5)(x - 7).

 

Explain why the functions f and h are not the same function.

To prove this, we can simply provide a counterexample. Let's input x=0. We see that for f(x)=(0+5)/(0-7), we have -5/7. For h(x), we have (0+5)(0-7)= -35.

 

Because -5/7 is not equal to -35, they are different functions.
