Please help m Part B: Write a polynomial expression that represents the total area of the swimming pool and walkway. To earn full credit, show your work using a method explained in the Orientation.
(please give explanation !!!)

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)

i dont know what you want me to answer for this but im guessing 2: 11?
