Lucy needs to buy some organic apples, and her grocery store is having a sale on them. if she buys 3 or fewer pounds of apples, the price will be $1.50 per pound. if she buys more than 3 pounds of apples, the price is $1.10 per pound. what is the domain of the piecewise-defined function, where x represents the number of pounds of apples?

To prove "p is equal to q" using an indirect proof, what would your starting assumption be?

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

Just tell me how to set up the equation.
