Question 639178

If we graph the function, we get

{{{ drawing(500, 500, -20, 20, -20, 20,
 graph( 500, 500, -20, 20, -20, 20,0,x^3 + 4x^2 + 7)

)}}}

So we can see that as x gets larger and larger in the positive direction, then f(x) will get larger and larger in the positive direction.


Also, as x gets larger and larger in the negative direction, then f(x) will get larger and larger in the negative direction.
