The formula for the volume of a cylinder with a height of 5 units is V(r) = 5pi2 where r is the radius of the cylinder. What is the dontain and range of this function?​

B-simple yes/no questions

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
