section 2.7: second derivative and concavity (h score: 20/80 answered: 2/8 question 4 the function graphed above is decreasing on the interval < x < the inflection point is at x = question help: video
Answer
Explanation:
Step1: Identify decreasing - interval
A function is decreasing when the slope of the tangent line is negative. Looking at the graph, the function is decreasing from $x=-3$ to $x = - 1$.
Step2: Identify inflection - point
An inflection point is where the concavity of the function changes. From the graph, the concavity changes at $x=-2$.
Answer:
-1. The function is decreasing on the interval $-3<x<-1$ -2. The inflection point is at $x = - 2$
