Answer
Explanation:
Step1: Recall local extrema concept
Local extrema are points where the function changes from increasing to decreasing (local maximum) or vice - versa (local minimum).
Step2: Identify furthest left local extrema from graph
By observing the graph, the furthest left local extrema occurs around $x=- 1$. Substitute $x = - 1$ into $f(x)=x^{5}-5x^{4}+10x^{3}-10x^{2}-2$: $f(-1)=(-1)^{5}-5(-1)^{4}+10(-1)^{3}-10(-1)^{2}-2=-1 - 5-10 - 10-2=-28$. So the furthest left local extrema is $(-1,-28)$.
Step3: Identify furthest right local extrema from graph
From the graph, the furthest right local extrema is given as $(3,-10)$.
Step4: Determine increasing intervals
A function is increasing when the slope of the tangent line is positive. From the graph, the function $f(x)$ is increasing on the intervals $(-\infty,-1)$ and $(1,3)\cup(3,\infty)$.
Step5: Determine decreasing intervals
A function is decreasing when the slope of the tangent line is negative. From the graph, the function $f(x)$ is decreasing on the intervals $(-1,1)$.
Answer:
Furthest left local extrema: $(-1,-28)$ Furthest right local extrema: $(3,-10)$ Increasing on the interval: $(-\infty,-1),(1,3)\cup(3,\infty)$ Decreasing on the interval: $(-1,1)$
