Question

This is a clarification question
Am I doing this right so far?
This is Graphing Quadratic Functions
First, you find the Axis Symmetry by using x=-b over 2a
Second, you put the x back into the original equation
Third, put the x and y together to make the vertex
Fourth, the C is the y-intercept, and then rewrite the y-intercept as 0 (zero), then the y-intercept
Then, graph the axis of symmetry, vertex, y-intercept, and the two other points

Answer 1

Here is an example of a problem \[y =x ^{2}-2\]

Answer 2

then after the x squared minus 2 there is minus 3

Answer 5

Ok then. I will teach you how I was taught to do it. @seiga

Answer 6

I am upload the pages right now @Pologirl19

Answer 7

Thanks again for trying to help me @e.cociuba

Answer 8

y=-4x squared +12x-5

Answer 9

@Pologirl19

Answer 10

\[x =\frac{ -12}{ 2 (-4) } = \frac{ -12 }{ -8}=\frac{ 3 }{ 2 }=1.5 \]

Answer 11

\[y =-4(1.5^{2})+12(1.5)-5=-4(2.25)+18-5=-10+18-5=8-5=3\]

Answer 12

2 minutes ago I did the first step
A few moments ago I did the second step

Answer 13

\[(1.5,3) Vertex y-intercept Rewrite y-intercept as (0,-5)\]

Answer 14

\[Axis of Symmetry is 1.5\]

Answer 15

I will do the graph now

Answer 16

The 5th one where you plugging it in you said it was -10+18-5. It is -9+18-5. So then it would equal 4. not 3

Answer 17

-4*2.25=10.00 is what I got

Answer 18

My bad @Pologirl19

Answer 19

Thank you

Answer 20

K well everything I see is good so you are good

Answer 21

Thank you. @Pologirl19 Do you have any questions?

Answer 22

No I don't it was a clear to me

Answer 23

Ok @Pologirl19

Answer 24

np:)
