Question

Let f(x) = 9x - 7 and let g(t) = 2 - x. Evaluate the quantity fo- g(4).

Answer 1

f(x) = 9x - 7

g(x) = 2 - x

Let's evaluate the function f(x) for x = 0

f(0) = 9(0) - 7 = 0 - 7 = -7

Now, evaluate the function g(x) for x = 4:

g(4) = 2 - (4) = -2

Therefore:

f(0) - g(4) = -7 - (-2) = -7 + 2 = -5
