If f(x) = -5% - 4 and g(x) =-3x - 2, find (f - g)(x).
o a. (f-g)(x) = -5x – 3x - 6
o b. (f-9)(x) = 5x – 3x+ 2
o c. (8-9)(x) = -5x+3x-2
o d. (f- g)(x) = -2x - 2

The graph of f(x), shown below, resembles the graph of g(x) = x2, but it has been changed somewhat. which of the following could be the equation of f(x)?

The function f(x)= -(x+5)(x+1) is down. what is the range of the function?

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?
