A student named CJ wrote the vertex form equation for a quadratic function with a vertex at (2,3) and an -a -value of -1. vertex form: y=a(x+h)^2-k (h, k) = (2,3) a = -1 y= -(x+2)^2 -3. CJ was not correct on this. explain the mistakes .

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
