Find g(-3) g(2) g(4)

Stells [14]

Answer:

$\frac{1}{2}$ , 2 , 4

Step-by-step explanation:

x = - 3 ≠ 2 , then

g(- 3) = $\frac{1}{2}$ × (- 3)² - 4 = $\frac{1}{2}$ × 9 - 4 = $\frac{9}{2}$ - 4 = $\frac{1}{2}$

x = 2 then g(2) = 2

x = 4 ≠ 2 , then

g(4) = $\frac{1}{2}$ × 4² - 4 = $\frac{1}{2}$ × 16 - 4 = 8 - 4 = 4
