ST is 3x I think because if you look at the line between S and T it says 3x
Thanks. I’m not struggling or anything but thanks for the kind words.
Answer:
<u> x | y </u>
<u> -1 | 2 </u>
<u> -0.5 | -0.25</u>
<u> 0 | -1 </u>
<u> 0.5 | -0.25</u>
<u> 1 | 2 </u>
<u>The graph is attached.</u>
Step-by-step explanation:
You have the following function:
By definition, the input in the independent value and the output is the dependent value.
Therefore, you must give values to x (input values) and substitute them into the function to obtain y for each value (output values).
Then:
x=-1
![y=3(-1)^{2}-1=2](https://tex.z-dn.net/?f=y%3D3%28-1%29%5E%7B2%7D-1%3D2)
x=-0.5
![y=3(-0.5)^{2}-1=-0.25](https://tex.z-dn.net/?f=y%3D3%28-0.5%29%5E%7B2%7D-1%3D-0.25)
x=0
![y=3(0)^{2}-1=-1](https://tex.z-dn.net/?f=y%3D3%280%29%5E%7B2%7D-1%3D-1)
x=0.5
![y=3(0.5)^{2}-1=-0.25](https://tex.z-dn.net/?f=y%3D3%280.5%29%5E%7B2%7D-1%3D-0.25)
x=1
![y=3(1)^{2}-1=2](https://tex.z-dn.net/?f=y%3D3%281%29%5E%7B2%7D-1%3D2)
Table:
<u> x | y </u>
<u> -1 | 2 </u>
<u> -0.5 | -0.25</u>
<u> 0 | -1 </u>
<u> 0.5 | -0.25</u>
<u> 1 | 2 </u>
