15 pi: irrational
46.86 repeated: rational
15/19: rational
-2√6: irrational
Step-by-step explanation:

-√64: rational because it equals to -8
15 pi: has "pi" in it
46.86 repeated: as long as it's repeated, it's rational
15/19: fractions are usually rational
-2√6: √6 is cannot be rationalized
Answer: B
(0.5, 7), maximum; (2, 1), point of inflection; (3.5, –5), minimum
Critical points of a function are those points at which a line drawn tangent to the curve is horizontal or vertical. On the graph, maximum and minimum points look like peaks and valleys, respectively. Points of inflection that are critical points are places where the curve flattens out and changes from being bent upward to being bent downward or vice versa.
