Question

Given f(x) = 2x - 3, find f(8)
***EXPLANATION NEEDED***

Answer 1

f(8) = 13

Explanation:

Step 1: Plug in 8 for the value of x.

• 
  `f(8) = 2(8) - 3`

Step 2: Multiply 2 by 8.

• 
  `f(8) = 16 - 3`

Step 3: Subtract 3 from 16.

• 
  `f(8) = 13`

Therefore, f(8) = 13.

Answer 2

Explanation:

Hi there!

Given;

f(x) = 2x - 3

To find: f(8)

Replace 8 in each place where there is "x" in f(x).

or, f(8) = 2*8 -3

= 16-3

= 13

Therefore, f(8) = 13.

Hope it helps!
