sketch a graph of the quadratic function with the given vertex and through the given point.then write the equation of the parabola in vertex form.
1. vertex(-3,-2);point(1,2)
**
Standard form of equation parabola: y=A(x-h)^2+k, (h,k)=(x,y) coordinates of the vertex.
For given parabola:
y=A(x+3)^2-2
find A using coordinates of given point (1,2)
2=A(1+3)^2-2
4=A(4)^2
A=4/16
equation:(1/4)(x+3)^2-2
see graph below:
