Consider the function p(t) shown, state the intervals on which the function is increasing. A) t < 1 and 3 < t < 4 C) 1 < t < 3 and t > 4 B) t < 1 and 3 < t < 5 D) 0 < t < 2 and t > 5

Step-by-step explanation:

If f′(x) > 0, then f is increasing on the interval, and if f′(x) < 0, then f is decreasing on the interval. This and other information may be used to show a reasonably accurate sketch of the graph of the function. Example 1: For f(x) = x 4 − 8 x 2 determine all intervals where f is increasing or decreasing.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

the correct answer is $7.38
