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