a product has a productin cost function C(x)180x+6210 and a revenue function R(x)=225x. Find and analyze the break even quantity then find the profit function.

The break even quantity is when the cost function (cost to buy products) is equal to the revenue function (money obtained from sales) and at this point, you have neither profit nor loss, hence, the term 'break-even'.

The profit function is when you have more money from sales than it costs to buy the products. The excess money is the profit. Hence, the revenue function here is greater than the cost function.

Can you give your question an attempt now? :)
