Assume that f is a polynomial and x=10 is a critical number for f. If
f′′(10)=−√2,
what do we conclude from the Second Derivative Test?

A) f has a local maximum at x=10
B) f has a local minimum at x=10
C) f has inflection point at x=10
D) f is concave up for x>10
E) f is concave down for x>10

Tcan be concluded that % of the seniors would prefer to see more candid pictures in this year's edition of the yearbook.

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
