# How do you graph #y=-3x^2-4x#?

##### 1 Answer

You'll get a parabola.

#### Explanation:

This function is a Quadratic (maximum degree of

Observing the coefficient of

Now let us try to find interesting points of your parabola that will help us to plot it:

1] y-intercept:

set

2] x-intercept:

set

so you have two solutions:

so the x- intercepts will be:

3] Vertex: this point represents the highest point reached by your parabola. the function can be written as

where in your case:

The

The
