Answer :
x = -2; 3x − 12 = -6 - 12 = -18
x = 2; 3x − 12 = 6 - 12 = -6
answer
C. {-18, -6}
x = 2; 3x − 12 = 6 - 12 = -6
answer
C. {-18, -6}
Answer:
the range is {-18,-6} for domain {-2,2}
Step-by-step explanation:
find the range of the function [tex]f(x) = 3x - 12[/tex] for the given domain
domain {-2, 2}
LEts find range f(x) when x=-2, plug in -2 for x in f(x)
[tex]f(x) = 3x - 12[/tex]
[tex]f(x) = 3(-2) - 12=-18[/tex]
LEts find range f(x) when x=2, plug in 2 for x in f(x)
[tex]f(x) = 3x - 12[/tex]
[tex]f(x) = 3(2) - 12=-6[/tex]
So the range is {-18,-6} for domain {-2,2}
