Question

f(x) = 2x+3 and g(x) = x - 7. Find f(3)

Answer 1

ANSWER

f(3) = 9

EXPLANATION

We are given the function:

f(x) = 2x + 3

We want to find f(3).

To do this, we have to replace x with 3 in the function and then simplify:

f(3) = 2(3) + 3

f(3) = 6 + 3

f(3) = 9

That is the value of f(3).
