Question

HELP!!!
Please help me!!!
the function y=-.03(x-14)^2+6 models the jump of a red kangaroo where x is the horizontal distance in feet and y is the corresponding height in feet. What is the kangaroos maximum height? How long is the kangaroo's jump

Answer 1

do you know anything about getting maximums?

Answer 2

no is that when you get the highest number on a parabola?

Answer 3

uuh do you know how to do this? um is the maximum height the vertex?

Answer 4

Yes that would be the maximum. Sorry I was busy for a second

Answer 5

oh thats ok im just glad im not by myself on this problem:/ and to get the vertex we just graph right?

Answer 6

so you can find the x value and then plug it back into the equation to get the y value which is what you are looking for

Answer 7

i guess but to get the x do what do we do? -b/2a?

Answer 8

You can graph it if you want but that decimal may be a problem

Answer 9

thats true

Answer 10

yup -b/2a

Answer 11

ok and then simplify from then on right?

Answer 12

and it would probably help to factor in the -.3 and then foil the problem so finding the distance can be easier

Answer 13

yes

Answer 14

oooh ok i think i get how to do it now! mind blown!!! thank you!!!!!XD

Answer 15

haha yay! your welcome...and I meant -.03 not -.3 but you get what im saying :)

Answer 16

yup yup thank you!!!

Answer 17

your welcome
