Hello, can you help me please​

Step-by-step explanation:

1. C(x) is in vertex form so let write the function out.

B is our maximum value so b=9.

To find a, we know that when x=5 is a root so plug 5 in for x to find a.

2.. Let convert Chelesa function into. standard form.

Let see which value has the higher constant.

135/16 is more than 8 so Chelsea jumper higher.

3. Set Herritea equation equal to zero.

Multiply both sides by the reciprocal of negative 2/9.

We talking positive distance so the answer is she has moved 6 units horinzontial.

4. The domain of C is all real numbers and the range is All real numbers that are less than or equal to 9.

The domain of H is all real numbers, the range of H is all real numbers that are less than or equal to 8.

5. That means that the y values are equal when x=3.7

goog may have it for you
