Question

F (x) = 5x - 1, find f (4) - show work

Answer 1

F(4)=19 is the answer

F(x)=5-1
F(4)=5(4)-1

Answer 2

f(4) = 19

Explanation:

Plug in 4 for x in the given equation:

f(x) = 5x - 1

f(4) = 5(4) - 1

Simplify. Remember to follow the order of operations, PEMDAS. First multiply, then subtract:

f(4) = (5 * 4) - 1

f(4) = 20 - 1

f(4) = 19

f(4) = 19 is your answer.
