Can you me im not that good at math and its a clear photo y =+__x+

So before I put the equation into standard form, I'm first going to be putting it into vertex form. Since the vertex appears to be (-1,7), plug that into the vertex form formula:

Next, we need to solve for a. Looking at this graph, another point that is in this line is the y-intercept (0,5). Plug (0,5) into the x and y placeholders and solve for a as such:

Now we know that our vertex form equation is y = -2(x + 1)^2 + 7.

However, we need to convert this into standard form still, and we can do it as such:

Firstly, solve the exponent:

Next, foil -2(x^2+2x+1):

Next, combine like terms and your final answer will be:

the answer is d. 75%

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
