Question

Choose all of the following equations that have a vertex that is the MINIMUM point of the parabola.
y = x2 + 2x + 4
y = -16x2 + 2x - 4
y = 2x2 + 2x + 8
y = -x2 - 4x - 3

Answer 1

ohh so this is actually very similar to the last one!

Answer 2

these graohs either look like this:

Answer 3

not sure . this is minimum & that was downward & unless they mean the same thing i don't know

Answer 4

or like this:

Answer 5

for this one the minimum would be right here:

Answer 6

beacuse thats the lowest point and the smallest possible y value

Answer 7

we want to identify the graphs that look like this

Answer 8

these are the graphs the open upwards

Answer 9

which ones would you say open upwards?

Answer 10

a & c ?
