What is the range if f(x) =1/2x - 2 and domain: -1/2,0,3,5,9 ?

The Range of $f (x)$ $f(x)$ with the given Domain is ${- 2.25, - 2, - 0.5, 0.5, 2.5}$ ${-2.25, -2, -0.5, 0.5, 2.5}$

Explanation:

Given the Domain ${- \frac{1}{2}, 0, 3, 5, 9}$ ${-1/2, 0, 3, 5, 9}$ for a function $f (x) = \frac{1}{2} x - 2$ $f(x) = 1/2x-2$

the Range of $f (x)$ $f(x)$ (by definition) is

${f (- \frac{1}{2}), f (0), f (3), f (5), f (9)}$ ${f(-1/2), f(0), f(3), f(5), f(9)}$

$= {- 2.25, - 2, - 0.5, 0.5, 2.5}$ $={-2.25, -2, -0.5, 0.5, 2.5}$
