Question

If f(x) = 6x - 4, what is f(x) when x = 8?

Answer 1

The answer is 44
f(x) = 6*x - 4
f(8) = 6*8 - 4
f(8) = 48 - 4
f(8) = 44

Answer 2

The answer is 44

To find this answer, we replace x with 8 and use PEMDAS (order of operations) to simplify

f(x) = 6*x - 4
f(8) = 6*8 - 4
f(8) = 48 - 4
f(8) = 44
