What is the range of g (x) = - 2x + 3, if the domain is {-2, - 1,0, 1, 2}?

{ - 1, 1, 7, 23 }

Step-by-step explanation:

To find the range substitute the values from the domain into g (x)

g (-2) = - 2 ( - 2) + 3 = 4 + 3 = 7

g ( - 10) = - 2 ( - 10) + 3 = 20 + 3 = 23

g (1) = - 2 (1) + 3 = - 2 + 3 = 1

g (2) = - 2 (2) + 3 = - 4 + 3 = - 1

Range is { - 1, 1, 7, 23 }
