Question

What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?

Answer 1

{24, 18, 12, 6, 0} is the range of the above function

Explanation:

solution:

let, x= -4

f(-2) = 12-3*(-2)

= 12+12

=24

let,x= -2

f(-2) = 12-3*(-2)

=12+6

18

let,x =0

f(0)= 12-3*0

=12-0

=12

let,x=2

f(2) = 12-3*2

=12-6

=6

let,x=4

f(4) = 12-3*4

=12-12

=0
