Question

Find the output (y) of the function y=6x+4 if the input (x) is 2

Answer 1

f(2) = 16

or

y = 16

Explanation:

Step 1: Write out function

y = 6x + 4

Step 2: Define variable for problem

x = 2

Step 3: Plug into function f(x)

f(2) = 6(2) + 4

f(2) = 12 + 4

f(2) = 16

Step 4: Change f(2) to y

y = 16
