Question

directions: given each function and domain, fi1. y = 5x - 9; domain = {1, 3, 7}

Explanation:

Step1: Substitute $x=1$ into function

$y = 5(1) - 9 = 5 - 9 = -4$

Step2: Substitute $x=3$ into function

$y = 5(3) - 9 = 15 - 9 = 6$

Step3: Substitute $x=7$ into function

$y = 5(7) - 9 = 35 - 9 = 26$

Step4: Collect all resulting $y$-values

The range is the set of calculated $y$ values.

Answer:

$\{-4, 6, 26\}$
