Step-by-step explanation:

Hi there! The answer is n = 10.

As you see at the powers of x, we need to add the exponents of the power we when multiply them.

The powers of y work the same way.

Hence, n = 10, since
(3x-4)(5x^2-2x+6)
15x^3-6x^2+18x-20x^2+8x-24
15x^3-26x^2+26x-24
Check the picture below, so the distance of the house from the other side is that blue gap.
so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.
Answer:
1. No.

Since f(1)=f(3) and
then f isn't one-to-one.
2. No

Since f(0)=f(2) and
then f isn't one-to-one.
3. No

Since f(0)=f(2) and
then f isn't one-to-one.
4. Yes

Since
, then f is one-to-one
5. Since f(1)=f(3) and
then, f isn't one-to-one
