Question

ain, find the range values.

1. $y = x^2 - 2x$; domain $= \\{-3, 0, 5\\}$

Explanation:

Step1: Substitute $x=-3$ into $y$

$y = (-3)^2 - 2(-3) = 9 + 6 = 15$

Step2: Substitute $x=0$ into $y$

$y = (0)^2 - 2(0) = 0 - 0 = 0$

Step3: Substitute $x=5$ into $y$

$y = (5)^2 - 2(5) = 25 - 10 = 15$

Answer:

$\{0, 15\}$
