Question

Find all real values of x for which f(x) = 0.

 (Enter your answers as a comma-separated list.)

f(x) = 4x − 5

7

Answer 1

It's the denominator

the 7 is the denominator...

I've seen the same thing happen in difference quotient problems, with h in the denominator

(4x-5)/7 = 0

4x-5 = 0

4x =5

x = 5/4
