Determine whether the lines l1 and l2 are parallel, skew, or intersecting. l1: x 1 = y − 1 2 = z − 2 3 l2: x − 3 −3 = y − 7 −4 = z + 1 6

Over which interval(s) is the function decreasing?

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
