WebOne approach is to divide up the interval and use n left or right samples of the value of the function, add them up, then divide by n. If we take the limit as n approaches infinity, then we will get the average value. The formula for the average value of a function, f, over the interval from a to b is: One way to think about this is to rewrite ...

It is a normal positive parabola with the vertex at ( 3, 0). The equation could be y = ( x − 3) 2, but my confusion comes from the interval on which the parabola is increasing: I would think increasing is ( 3, ∞) and decreasing is ( − ∞, 3).

WebThe parentheses tell you that the inequalities do not include the end values of -2 and 5.
