Let f be a continuous function on [−3,3], and suppose 7 is the absolute maximum value of f on [−3,3]. Using properties of integrals, this tells us that ∫3,−3 f(x)dx≤−−−. What number goes in the blank?

please help..

-3 to + 3 = 6 long

The biggest it could be is a rectangle 6 long and 7 high
6 * 7 = 42
