Question

Graph the function f(x) = (x + 3)3 by hand and describe the end behavior?

Answer 1

Is (x+3) cubed?

Answer 2

yes

Answer 3

If you expand that it would be equal to x^3+9x^2+27x+27
Using the lead coefficient x^3
The coefficient of x is positive raised to an odd exponent
So the the graph would be falling down at the left end and rises at the right end
