Question

A student graphed the polynomial function P(x) = 2x3 + 9x2 − 27 on a computer, as shown below.

Polynomial function coming up from the left to the turning point at negative three comma zero and going down to the turning point at zero comma negative twenty seven and going up through the point at approximately one and one half comma zero and continuing towards infinity

Part A: Using synthetic division, what is the fully factored form of the polynomial shown above?

Part B: Describe the polynomial function in terms of zeros, multiplicity, y-intercept, degree, and end behavior.

Answer 2

Hey @some.random.cool.kid im sorry but im not good at that sorry have a great day :)

Answer 3

ok

Answer 4

@IrishBoy123 @imqwerty @inkyvoyd @tkhunny Do you guys know how to do this type of math?

Answer 5

from your graph, when does P(x) = 0?

Answer 6

uh, at -27 maybe?, not sure actually.

Answer 7

would be pleased if you could explain this?

Answer 8

plot it

the answer is usually -1 or something really easy to work with. there is a pattern in there : 2, 9 , 27

but you have to plot it yourself first to be "that student". then it's just mechanical.

Answer 9

oh my, got it thanks man/sir/irish?
