Please Help I am having one of those dumb moments.

Which of the following equations is an example of inverse variation between the values x and y?

Explanation: C

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
