How do I find the inverse of this problem?

Actually Welcome to the Concept of the Inverse of real function.

Let's consider here, g(n) = y ,

so we get as,

no, cubing the power both side we get as,

=>

now,

so finally, we get as,

=>

hence,here, n = inverse of the g(n) function.

so,

g^-1 (n) = 2y^3+1.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
