A student claims that the function f(x) = 3x^4 – x^3 +7 is a fourth-degree polynomial with end behavior of down and down. Describe the error the student made. What is wrong with this statement?

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
