Question

use the function rule f (x) = 3x - 2 find the output f (1.5)
2.5
-2.5
6.5
-6.5

Answer 1

First plug in f(1.5) which is the same thing as f(3/2).

f(3/2) = 3(3/2) -2 = 9/2 -2

multiply the -2 by 2 on the top and bottom to give it the same denominator

f(3/2) = 9/2 - 4/2 = 5/2

which is f(1.5) = 2.5

Answer 2
