Question

First picture is by itself. Next is graph problem :)

Answer 1

1). g(-9) = -81.914

2). Last option

Explanation:

1). f(x) = x²

For x = -9

f(-9) = (-9)² = 81

g(x) =
`(32)/(2x-17)`

g(-9) =
`(32)/([2(-9)-17])`

=
`(32)/(-35)`

= -
`(32)/(35)`

(g - f)(-9) = g(-9) - f(-9)

=
`-(32)/(35)-81`

=
`(-32-2835)/(35)`

=
`-(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.
