Question

The function f(x) = -x + 5 has domain values of -3, 3, and 9.

Which are the corresponding range values?

A 3,7, and 11

B 7,3, and -1

C 9,3, and -3

D 12,3, and -6

help!

Answer 1

A 3,7, and 11

Explanation:

Domain is the x-value so you replace all the x's in f(x)=-x+5 with -3,3, and 9

f(-3)=2/3(-3)+5

= 3

f(3)=2/3(3)+5

=7

f(9)=2/3(9)+5

=11

Hope this helps!
