For the function g(x)=2xcubed + 5xsquared - 28x - 15

a) Determine the maximum number of real zeros that the function may have.

I answered 3

b)Determine if (x-3) is a factor.

I answered yes.

c)List the potential rational zeros.

?

d) Determine the real zeros of g

?

e) Find the x and y intercepts.

I answered y intercept= -15 and x intercepts= -5, 3

f) Determine if the graph touches or crosses the x-axis at the intercepts

?

g) Find the power function that the graph resembles for large values of absolute value x (end behavior).

?

Just wondering if I did the few I answered right and how to do the other ones. Thanks!
