Someone please help me I’m having trouble

(c) and

(d)

Step-by-step explanation:

Given

See attachment

First, we complete the table

So, we have:

Solving (c): Between which values is y

The values of y are for both equations are closest at:

and

Hence, the solution is between

and

Solving (d): Approximated value of the solution

We have:

So:

Collect like terms

Divide both sides by 3

Substitute in

So, the solution is:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
