![(-1,-72)](https://tex.z-dn.net/?f=%28-1%2C-72%29)
![(-1, -\frac{575}{8} )](https://tex.z-dn.net/?f=%28-1%2C%20-%5Cfrac%7B575%7D%7B8%7D%20%29)
![x=-1](https://tex.z-dn.net/?f=x%3D-1)
![y=-\frac{577}{8}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B577%7D%7B8%7D)
Factor the polynomial completely.
Group and factor out the greatest common factor (GCF), then combine.
Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Let's solve your equation step-by-step.
−3x2−4x−4=0
Step 1: Use quadratic formula with a=-3, b=-4, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−4)±√(−4)2−4(−3)(−4)
2(−3)
x=
4±√−32
−6
Answer:
No real solutions.
Answer: 80
Write down all the values and cross out until you get to the middle, since there are 2 values, find the mean, which would be 80
Answer:
The graph should be stretched rather than become narrower.
Step-by-step explanation:
To figure this out, just create some example points.
At x = 0, your y-value will always be 0. But if you were to plug in the value 1, you would get a y-value of 1 in y=x^2, but a value of 0.5 in y=0.5x^2. If you were to plug in a value of 2, you would get a value of 4 in y=x^2, but a value of 2 in y=0.5x^2.
If you continue this pattern for a few more points, then plot them, you will see that adding a coefficient of 0.5 simply stretches the graph
