The functions f and g are defined as follows.

f(x)=-2x to the third power -3 g(x)=-2x-3

Find f(-2) and g(5) .


Simplify your answers as much as possible.

Answer :

Step-by-step explanation:

Given that,

[tex]f(x)=-2x^{-3}\ ......(1)\\\\g(x)=-2x-3\ ......(2)[/tex]

Put x = -2 to find f(-2) in equation (1).

[tex]f(-2)=-2(-2)^{-3}\\\\=\dfrac{1}{4}[/tex]

Put x = 5 to find g(5) in equation (2).

So,

[tex]g(5)=-2(5)-3\\\\=-13[/tex]

Hence, f(-2) = 1/4 and g(5) = -13.
