PLEASE HELP I AM DESPERATE 2-Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, t-intercept, and zeros.
g(x)=(x+2)(x-1)(x-2)
g(x)=(x+3)(x+2)(x-3)
g(x)=(x+2)(x-2)(x-3)
g(x)=(x+5)(x+2)(x-5)
g(x)=(x+7)(x+1)(x-1)

PART B
4- Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x)=(x-a)(x-b). Describe the direction of the parabola and determine the y-intercept and zeros.
5- Create a graph of the polynomial function you created in Question 4

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
