Question

A function is shown: f(x)= 2/3x+3
What is the value of f(18)?

Answer 1

The value is of f(18) is 15.

Answer 2

15

Explanation:

When you see something like f (18), this means 18 needs to be plugged in for x

let's plug in 18

f (18) =
`(2)/(3) (18) + 3`

Let's solve

(18 × 2) ÷ 3 = 12

12 + 3 = 15

f (18) = 15
