Answer:
vertex form automatically gives you your vertex and your y intercept so all you need to do is graph. Hope this helps
Step-by-step explanation:
Step-by-step explanation:
oh, come on. you can just use common sense.
a local minimum is a point where the curve goes down to, and then turns around and starts to go up again. that point in the middle, where it turns around and does not go down any further, is the minimum.
for the maximum the same thing applies, just in the other direction (the curve goes up and turns around to go back down again).
a)
the local minimum values (y) are
-2, -1
b)
the values of x where it had these minimum values are
-1, +3
600 * .34 = 204 are in 8th grade
204 * 1/4 = 51 51 8th graders walk to school
D
The probability is 7/10.
There are 14 outcomes in this simulation with fewer than 3 left turns, out of 20 times the simulation was run:
14/20 = 7/10
