WebThe second derivative of a function may also be used to determine the general shape of its graph on selected intervals. A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval. If a function changes from concave upward to concave downward … WebProblem-Solving Strategy: Using the First Derivative Test. Consider a function f f that is continuous over an interval I. I..

WebProcedure to find where the function is increasing or decreasing : Find the first derivative. Then set f' (x) = 0. Put solutions on the number line. Separate the intervals. Choose random value from the interval and check them in the first derivative. If f (x) > 0, then the function is increasing in that particular interval. WebIf you mean that you let x=0, then f (0) = 0^2-4*0 then this does equal 0. So, f (0)=0. This function decreases over an interval and increases over different intervals.

Webf(x) = cos2 x−2sinx, 0 ≤ x ≤ 2π. (a) Find the intervals on which f is increasing or decreasing. Answer: To ﬁnd the intervals on which f is increasing or decreasing, take the derivative of f: f0(x) = 2cosx(−sinx)−2cosx = −2cosx(sinx+1). Since sinx+1 ≥ 0 for all x, we see that the sign of f0(x) is the opposite of that of cosx. WebA. Find all values of x in the interval [0, 2?] that satisfy the equation.
