Answer 10

Read the hint for part B. Profit is difference between revenue and cost. Difference means subtraction.

P(x) = R(x) - C(x)

so plug in the R and C functions, and simplify.

Answer 11

For C, remember that the vertex is the max value of a quadratic. Remember to find the vertex, use\[\large x = -\frac{ b }{2a }\]and then you plug that into the equation to find the y-value.

Answer 12

That is for an function of the form \[\large y = ax^2 +bx +c\]
