The test pt. 2

Next she had to solve a system of non-linear equation with a table:
y=x^2 , y=8-x^2
y=x^2=y=8-x^2
x^2=8-x^2

x^2=8-x^2
2x^2=8
2/2x^2=8/2
x^2=4
x=-2,+2

x=-2
y=x^2
y=(-2)^2=4

x=+2
y=x^2
y=(+2)^2=4

The meet at (-2,4) (2,4)

After that she had to Compare linear, quadratic, and exponential growth functions using a table and a graph. Submit the graph and table.
Linear functions take the form y=mx+b  Quadratic functions take the form y=ax^2+bx+c   Exponential functions form y=a*b^x
