Answer 1

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) = $\frac{32}{2x-17}$

   g(-9) = $\frac{32}{[2(-9)-17]}$

           = $\frac{32}{-35}$

           = - $\frac{32}{35}$    

   (g - f)(-9) = g(-9) - f(-9)

                  = $-\frac{32}{35}-81$

                  = $\frac{-32-2835}{35}$

                  = $-\frac{2867}{35}$

                  = -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.
