Answer:
1). g(-9) = -81.914
2). Last option
Step-by-step explanation:
1). f(x) = x²
For x = -9
f(-9) = (-9)² = 81
g(x) = [tex]\frac{32}{2x-17}[/tex]
g(-9) = [tex]\frac{32}{[2(-9)-17]}[/tex]
= [tex]\frac{32}{-35}[/tex]
= - [tex]\frac{32}{35}[/tex]
(g - f)(-9) = g(-9) - f(-9)
= [tex]-\frac{32}{35}-81[/tex]
= [tex]\frac{-32-2835}{35}[/tex]
= [tex]-\frac{2867}{35}[/tex]
= -81.914
2). The relation is not a function because this function doesn't passes a vertical line test.
Last option will be the answer.
