Question

y = –2x² + 2
y = –x²
y = 2x²
y = 3x² – 4

Answer 1

so...

Answer 2

What's the question?

Answer 3

graph please

Answer 4

Place values in x and y so that

when x = 0, y = ?
or when y = 0, x = ?

So that you can plot.

Answer 5

for the first one

Answer 6

(If the link doesn't work..) If you type "plot y = –2x^2 + 2 " into the question space, it will plot it for you to check your answers.

+2 is the Y intercept. Then use Order's method of plug and chug for values of x and y.

Answer 7

y=-2x^2
when y = 0

0=-2x^2+2
0=-22x^2
x^2=1
x=1

(1,0)

When x=0

y=-2(0)^2+2
y=2

(0,2)

Those are the points on the graph of the first equation

Answer 8

for the first equation
