Answer:
a) The startup cost of the company is the value of P when x equals zero.
Which is the P intercept on the graph.

b) The number of items they have to sell to break even is the value of x when the profit P equals zero.
This is the x-intercept on the graph.

c) The number of products they need to sell to maximize profit is the value of x at the maximum point on the graph.
This is the x coordinate of the vertex

Step-by-step explanation:
Given the revenue equation of the product;

Graphing the equation.
a) The startup cost of the company is the value of P when x equals zero.
Which is the P intercept on the graph.

b) The number of items they have to sell to break even is the value of x when the profit P equals zero.
This is the x-intercept on the graph.

c) The number of products they need to sell to maximize profit is the value of x at the maximum point on the graph.
This is the x coordinate of the vertex
