3. Subtract the polynomials.
(-3x + 3x3 - 2x2 + 2) - (8 - 4x + 3x2)

Let's simplify step-by-step.

−3x+3x3−2x2+2−(8−4x+3x2)

Distribute the Negative Sign:

=−3x+3x3−2x2+2+−1(8−4x+3x2)

=−3x+3x3+−2x2+2+(−1)(8)+−1(−4x)+−1(3x2)

=−3x+3x3+−2x2+2+−8+4x+−3x2

Combine Like Terms:

=−3x+3x3+−2x2+2+−8+4x+−3x2

=(3x3)+(−2x2+−3x2)+(−3x+4x)+(2+−8)

=3x3+−5x2+x+−6

=3x3−5x2+x−6

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
