Create and describe a function related to your field (or intended field). Give a detailed explanation of the domain (input) and range (output). Then, respond to the following. What values make up the domain? What values make up the range?
Does it make sense for the function to have a root? What would the root describe?
What would the x- and y-intercepts represent for your function?
Does it make sense for your function to have an inverse? Explain.
Describe a situation where your function becomes an equation that can be solved. Solve.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

First locate the turning point (vertex) of the graph. which is at the coordinates x=5 and y=9 or (5; 9).to determine whether it's a maximum or mininum value, you have to discern whether the vertex's y-value is the highest value or lowest value the graph can reach. since the vertex's y-value, 9 is the highest value the graph can reach, it will be a maximum.another basic way to determine whether the vertex's value is max or min is to see if the graph is smiling or sad. if it's smiling, the turning point/vertex would be a minimum, while a sad parabola would have a maximum y-value at the vertex.
