Given the domain values { -2, 0, 2 }, find the range values for the function y = 3x – 2.

{ 8, -2, 4 }

{ 12, 0, -12 }

none of the above

Answer 1

Answer 2

\[y = 3x - 2\]
\[y=3\times (-2)-2=-6-2=-8\]

Answer 3

so \(-8\) is in the range
now try with 0
\[y=3\times 0-2=0-2=-2\] and so \(-2\) is in the range

Answer 4

and finally
\[y=3\times 2-2=6-2=4\] and so \(4\) is in the range

Answer 5

clear what to do right?
