Find the range of the function rule y = 5x - 2 for the domain D = {-5, -1, 0 2, 10}

3 answers

range is [-27,48]
I have no idea how to solve this so please give me some advice
{–27, –7, –2, 8, 48}

Substitute each domain value into y = 5x – 2 to find the range values.

y = 5(–5) – 2 = –27

y = 5(–1) – 2 = –7

y = 5(0) – 2 = –2

y = 5(2) – 2 = 8

y = 5(10) – 2 = 48
