Question

For y=x^2-36, can someone tell me what the equation would look like sketched out on a graph? I am horrible with graphing and what the vertex would be?

Answer 1

Can you tell that it is a parabola shifted down 36 units?

Answer 2

The best thing to do is to make a table of \(x\) and \(y\) values and plot each point.

Answer 3

while drawing a graph,the points you get most easily are the ones for which the value of the other variable becomes zero.that is,values of x for which y is zero and vice versa.plot these points on the graph

Answer 4

since this is a quadratic equation,its graph will be a parabola.do you know how a parabola looks like?

Answer 5

I do know what one looks like

Answer 6

for y=0,x has two values 6,-6.and for x=0,y=-36

Answer 7

if you know how a parabola looks like,i am sure you can do the rest yourself

Answer 8

Yep! Can you tell me what the vertex is though?

Answer 9

0,-36

Answer 10

are you still having some problem?

Answer 11

Yes sorry my computer froze.
