WebDetermine dimension x to 3 decimal places. Find the local extrema of f (x)= (x-1)^2 / x^2+1 Using first/second derivative test. Find two positive numbers so that the sum of the first and twice the second is 100 and the product is a maximum. (Use Second Derivative Test for maxima/minima to verify.) WebFinding the intervals where f ′ ( x) is positive (or negative), and hence where f ( x) is increasing (or decreasing) is closely related to critical numbers. Critical Numbers Recall that a critical number (also called a critical point) is a value of x where f is defined, and where f ′ ( x) is either zero or doesn't exist.
