OpenStudy (misty1212):
what kind of line is \(y=4\) horizontal or vertical ?
OpenStudy (anonymous):
Horizontal, right?
OpenStudy (misty1212):
yes, that means the parabola opens up or down, and it means the x term is squared

now go ahead and draw the line \(y=4\) and plot the vertex \((0,0)\)
OpenStudy (misty1212):
lol too many vertical lines
OpenStudy (anonymous):
Ohh so it'd be just one this time?
OpenStudy (anonymous):

OpenStudy (anonymous):
I am unsure. Thought there was an example on the last problem.
