Question

F(x) = -7x - 1 f() = -8

Answer 1

Answer:

  f(1) = -8

Step-by-step explanation:

Apparently, you want the argument of the function such that the function value is -8. Fill in the given information and solve for x:

  -8 = -7x -1

  -7 = -7x . . . . add 1

  1 = x . . . . . . . divide by -7

Now, you know that ...

  f(1) = -8
