-5x^4(-3x^2+4x-2)

15x^6 − 20x^5 + 10x^4

Step-by-step explanation:

You distribute the -5x^4 across −3x^2+4x−2 then you add the exponents, remember that there is an "x" with no exponent counts as 1 so when you add the four from "-5x^4" just add one.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
