Question

graph the following quadratic equation:
y+12+x^2=4x^2-7x

Answer 1

y=3x^2-7x-12

Answer 2

ok i have that but i dont know how to graph it
'

Answer 3

x=-b/2a=7/6. So the x coordinate of the vertex is 7/6. Now plug 7/6 in to find the y coordinate of the vertex

Answer 4

So the vertex is (7/6,-14 11/12)

Answer 5

Vertex is (7/6,-16 1/12)

Answer 6

Now choose an x value to the right of 7/6 like 2 and plug it in to find y.

Answer 7

You will get (2,-14)

Answer 8

Use symmetry to get the corresponding point to the left of the vertex.

Answer 9

Now choose another x value perhaps 3 and plug it in. You will get -6. So graph (3,-6). Graph the corresponding point to the left of the vertex. That should be enough to draw the curve.

Answer 10

i am so lost'

Answer 11

Two versions of the plotted quadratic expression is attached.

Answer 12

ok thank you

Answer 13

So money, do you still need help?

Answer 14

I see you said you are so lost.

Answer 15

no i got it

Answer 16

ok
