Answer:

{-4,2,11}

Explanation:

The Range of the function f(x) = 3x + 2, are the values of "y", when you replace "x" by -2, 0 and 3.

When x = -2:

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

f(-2) = -6 +2

f(-2) = -4

y = -4

When x = 0:

f(0) = 3 (0) + 2

f(0) = 0 +2

f(0) = 2

y = 2

When x = 3:

f(3) = 3 (3) +2

f(3) = 9 +2

f(3) = 11

y = 11

So, the Range is {-4,2,11}
