Answer to: Find the intervals on which the function is increasing and the intervals on which it is decreasing. f(x) = - \frac {x^4}{4} + x^3 - x^2...
Step 1: Understand the condition for increasing functionA function f(x) is increasing on an interval if its derivative f′(x) is greater than zero for all x in that interval. Step 2: Differentiate the functionWe differentiate f(x):f′(x)=ddx(x2+ax+1)=2x+aStep...
Plug each test point into the derivative of the function and evaluate. If the test point gives a positive output, then the function is increasing on the interval from which it came. If the test point gives a negative output, then the function is decreasing on th...
Question: Find the intervals on which f(x) is increasing, the intervals on which f(x) is decreasing, and the local extrema.f(x)=-4x2-32x-21A. The function is increasing on ◻ .(Type your answer in interval notation. Type intege...
To find the intervals on which the function f(x)=xx2+1 is increasing or decreasing, we will follow these steps: Step 1: Find the derivative of the functionTo determine where the function is increasing or decreasing, we first need to find its derivative f′(x). ...
