Answer:

x = -4

Step-by-step explanation:

Start by replacing f(x) with -1.

-1 = 2x + 7

Then subtract 7 on both sides of the equation and add like terms.

-8 = 2x

Then divide 2 on both sides of the equation and solve.

-4 = x

f(x) is -1 which means x is -1 so you times 2 x -1 and that is -2 then you add -2+7 which is 5. so your answer would be 5
