Question

The graph of which quadratic equation is shown below?

y = x^2 + 2x − 8

y = x^2 − 2x − 8

y = −x^2 − 2x + 8

y = −x^2 − 4x − 8

Answer 1

Answer 2

Hmm not sure D:

Answer 3

Does the graph of x^2 open up or down? How about -x^2?

:)

Answer 4

as its -x^2 it will be open downwards like C and D

Answer 5

f(x) + C will affect the position on the y axis. Take this fact into consideration.

Answer 6

yup

the intercept on y-axis is when x = 0

Answer 7

can you find the x -intercepts?
