Answer 2

when x = 0, y = -2...so it has a y-intercept at y = -2

Answer 3

wait but how do u get the other points>?

Answer 4

well... the graph of y = x^3 is a classical function whose graph is:

Answer 5

so y = - x^3 is the reflection of x^3 over the x-axis...so -x^3 looks like:

Answer 6

so the graph of y = - x^3 - 2 is the graph of y = - x^3 just lowered 2 units!

Answer 7

how about this equation" g(x) =x^4 +2x

Answer 8

You're welcome.
