Answer:
, 
Step-by-step explanation:
The total area of the pool and the walkway is:
The roots of the second-order polynomial is:
and 
The only possible root is:
The other dimension of the pool is:
It would be about 16.67 for a regular price of the Vans?
f(0) means the function output when the input is x = 0. This is the same as saying the y value when x = 0.
f(x) = 3-2x
f(0) = 3-2(0)
f(0) = 3
The point (0,3) is on the graph. This is the y intercept which is where the graph crosses the y axis. The y intercept always occurs when x = 0.
So in other words, the special name for f(0) is the y intercept.
I can answer most of them!
