Question

How do you use the important points to sketch the graph of `y=-3x^2-4x`?

Answer 1

`y=-3x^2-4x`

Explanation:

If `x=0` your function will be `y=0`
If your `x=1` your function will be `y=-7`
If your `x=-1` your function will be `y=1`

You can graph based on these values. graph{(-3x^2)-(4x) [-5, 5, -10, 2.5]}
