May I have some help with Algebra II!
@tkhunny can you help me?
Post a problem. Show your work.
As one of the new roller coaster engineers, you have been tasked with developing a roller coaster that will intertwine with existing Oakville Lake Amusement Park structures. For one of the more thrilling sections, the roller coaster will dive down in-between buildings, plummet underground, pop back up, and coast over a hill before shooting back underground. There must be three distinct points where the roller coaster crosses the x–axis. Precise measurements and attention to detail are very important.
1.Using the points above as zeros, construct the polynomial function, f(x), that will be the path of your roller coaster. Show all of your work.: The root 6 has a factor of (x-6), the root -2 has a factor of (x-(-2)), and the root -7 has a factor of (x-(-7)). Multiplying (x-6) and (x+2), I get x^2-4x-12. Then I multiply this by (x+7), so (x^2-4x-12)(x+7). This results in a function of f(x)=x^3 + x^2-28x-12x-84
I'm stuck on this... Using both fundamental Theorem and Descartes` rule of signs, prove to the construction foreman that your function matches your graph. Use complete sentences.:
Not sure where to help you. You seem to have the right idea. Given zeros at -7, -2, and 6, where is the graph when it is right over or under the obstacles? Make sure you have enough clearance.
I got it actually! Thanks anyways!
@Cubi-Cal Im on the same problem how'd you do it?
