Answer
f(-8) = 23
g(2) = -10
Explanation
f(x) = (-3x/2) + 11
g(x) = x² - 7x
h(x) = | 15 - 9x |
We're then told to calculate f(-8)
f(-8) refers to solving f(x) when x = -8
Recall
f(x) = (-3x/2) + 11
[tex]\begin{gathered} f(-8)=\frac{-3\times-8}{2}+11 \\ =\frac{24}{2}+11 \\ =12+11 \\ =23 \end{gathered}[/tex]f(-8) = 23
g(x) = x² - 7x
g(2) = 2² - (7 × 2)
= 4 - 14
= -10
g(2) = -10
Hope this Helps!!!
