Question

describe the shape of the graph of each cubic function by determining the end behavior and number of turning points y=x^3+2x

Answer 1

it is degree 3 with positive leading coefficient, so "end behaviour" is as \(x\to \infty, x^3+2x\to \infty\) and also \(x\to -\infty, x^3+2x\to -\infty\)

Answer 2

this one has no turning points, since all the coefficients are positive

Answer 3

thank you so much

Answer 4

can yu try explaining it again I don't really understand it @satellite73

Answer 5

do you know what i mean by "degree"?

Answer 6

yes
