help me find the x intercepts and y intercepts
the line of best fit
the vertex
and max and min
First off, graph it so you have a picture of what it looks like.
x-intercept:
Set y=0 and solve for x by using quadratic formula.
y-intercept:
Set x=0 and solve for y.
vertex:
Useto find the x and y coordinates of the vertex.
max or min:
For a parabola the max or min is at the vertex. This one is concave up, so it has a minimum.
