Question

GIVING OUT A METAL PLEASE HELP ME DO THIS!
I'LL FAN YOU TOO

Answer 1

with wat

Answer 2

Solve for the y–intercept for your function, f(x), and then graph your rollercoaster (you can use Geogebra). If your y–intercept is off the graph, give the coordinates of the y–intercept. f(x)= (x+6)(x+5)(x-6)

Answer 3

ok i will help u

Answer 4

tHANKS! :D its the last question i need c:

Answer 5

better. but remember they want rollercoaster will dive down in-between buildings, **** so show it starting high on the right plummet underground, **** OK pop back up, **** OK and coast over a hill *** OK before shooting back underground. *** show the path going back underground on the left

Answer 6

now pick 3 x values that (roughly) match that path

Answer 7

x has to be -12 or -13 so you don't go through the building if you pick x=-13, that looks safe so let's use x= 5, -4 and -13 a third-degree polynomial crosses the x-axis 3 times you can say y = (x-5)(x - -4)(x- -13) or y= (x-5)(x+4)(x+13) that will go through your points. It's y intercept is when x=0 or -5*14*13 = -910 that is very big. so let's multiply by 1/(14*13) = 1/182 that will make the y -intercept = -5

Answer 8

It's y intercept is when x=0 or -5*4*13 = -260 that is very big. so let's multiply by 1/(4*13) = 1/52 that will make the y -intercept = -5 y=(x-5)(x+4)(x+13) is ok, but it looks nicer if you divide by 52 y=(1/52) (x-5)(x+4)(x+13)

Answer 9

the red line is g(x) = x3 – 2x2 + 4x – 8, and the blue line is h(x) = x3 + 5x2 – 8x – 48.

Answer 10

Wouldn't -13 be point one since it's where the rollercoaster starts? **** they say "The rollercoaster will run from right to left," I think that means we start with the most positive x as the first point. now back to the problem of multiplying out the factors: *** x^2+4x-5x-20 ***** simplify 4 x's take away 5 x's gives -1x or just -x x^2 -x -20 now we do (x^2 -x -20)(x+13) you can "distribute" the (x+13)

Answer 11

did that help u

Answer 12

woah...what? lol

Answer 13

i already have those, i just need; Solve for the y–intercept for your function, f(x), and then graph your rollercoaster (you can use Geogebra). If your y–intercept is off the graph, give the coordinates of the y–intercept.

Answer 14

oh wrong crap

Answer 15

c: lol

Answer 16

i dont know this crap dang srry

Answer 17

:/ its okay

Answer 18

y-intercept should be when x=0
so plug in x=0 into (x+6)(x+5)(x-6)
so (0+6)(0+5)(0-6) = (what do you get?)
