Question

Does anyone know what f(x)=-5x-1 when f(-7) i need help with this please.

Answer 1

f(-7) = 34

Explanation:

If f(x) = -5x - 1, then . . .

f(x) = -5x - 1

f(-7) = -5(-7) - 1

= 35 - 1

= 34

. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.
