4. the space shuttle travels at about 28,000 km per hour. using that information, estimate how many hours it will take the shuttle to reach saturn from earth. (assume both planets are aligned with the sun and are on the same side of the sun.) show your work. convert your answer into scientific notation if necessary.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
