Answer:
A: y = -2x^2
Step-by-step explanation:
The parent function would be y = x^2 since it is a parabola.
Since the function has a vertical stretch by 2, y = 2x^2.
Finally, the function is inverted so the final equation would be y = -2x^2
So, since the question is asking you what percentage 31.5% is of 473, you can multiply 31.5 by 473 and get <span>14899.5. But, you'll have to change this answer into a percentage. So, you can move the decimal point two places over, and end up with 148.995. Since the question says that you can round to the nearest whole number, you can go ahead and put down 149. Hope this helped.</span>
