What equation does the graph of system of equations solve?

a. x2 − 2x − 1 = −x2 + 3
b. x2 − 2x + 3 = x2 − x + 1
c. −x2 − 2x + 2 = 2x2 − x − 2
d. −x2 − 2x + 1 = 2x2 − x + 2

ten points!

  a.  x^2 − 2x − 1 = −x^2 + 3

Step-by-step explanation:

The red curve in the figure is described by 3-x^2. The only answer choice that includes that expression is choice a.

___

The red curve is your basic y=x^2 curve reflected across the x-axis (y=-x^2) and shifted up 3 (y=-x^2+3).

Both curves go through the point that is 1 over and 1 up (or down) from the vertex, so the vertical scale factor is 1. That is, any choice with 2x^2 in it will not be an answer.

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
