Each day, a local cat shelter spends an average of $2.00 on food per cat. The manager estimates the shelter’s daily expenses, assuming there is at least one cat in the shelter, using the function E(x)= 25 + 2.00x.

Select all the statements below that are true.

• E(x) is the input

• 25 represents the shelter's daily nonfood expenses

• x represents the number of cats at the shelter

• 25 is the slope

• 25 is the constant term

Select all the statements that are true.
