HINT ***** is the lines point up or down and look at the vertex is a negative or a positive.

• The function is negative and decreasing on the interval.

• The function is positive and decreasing on the interval.

• The function is negative and increasing on the interval

• The function is positive and increasing on the interval

Hint there are 2 functions: Type the equation in desmos state the maximum amount. Then type the table in desmos and state the maxium amount. Then read what the question is saying to do with both maximum
