Answer:

Step-by-step explanation:

The equation of the parabola is of the form

y = ax² + c ( where c is the y- intercept )

Here c < 0

Since the parabola has a maximum value and opens down then a < 0

Thus the only equation that could represent this parabola is

y = - x² - 3 → D

1. a=-1+b/7 is the right answer. First you had to add by b from both sides of equation, and it gave us, $7a-b+b=-1+b$ . And then simplify, and it gave us, $7a=-1+b$ . Divide by 7 from both sides of equation, and it gave us, $\frac{7a}{7}=-\frac{1}{7}+ \frac{b}{7}$ . Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer.

2. a=-b-1/2 is the right answer. First you had to add by 2b from both sides of equation, and it gave us, $-4a-2b+2b=-2+2b$ . And then simplify, and it gave us, $-4a=-2+2b$ . Next you can also divide by -4 from both sides of equation, and it gave us, $\frac{-4a}{-4}=-\frac{2}{-4}+\frac{2b}{-4}$ . Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer.
