Question

Can someone please help me in finding the range

Answer 1

`\{-20, -2 ,13\}`

Explanation:

The range of a function is the set of its possible output values

`f(x) = 3x-8\\\\f(-4) = 3(-4) -8 = -12 -8 = -20\\\\f(2) = 3(2) -8 =6-8 = -2\\ \\f(7) = 3(7) -8 = 21 -8 = 13\\\\\text{Range} = \{-20, -2 ,13\}`
