Morevoer, since f'(x)0 in (infinity, 1) u (3,5), we see that f is decreasing in (infinity, 1) u (3,5) Example 2 Suppose f'(x) = (x1)(x3)(x7) , then f'(x)>0 in (infinity, 1) u (3,7) and hence f is increasing in those intervals On the other hand, f'(x)0 in (1,3) union (7, infinity), so f · Separate the intervals 0, π/2 to sub intervals in which f(x) = sin 4 x cos 4 x is increasing or decreasing(ii) lim x> x 0 f(x) exists (iii) f(x 0) = lim x > x 0 f(x) To know the points to be remembered in order to decide whether the function is continuous at particular point or not, you may look into the page " How to Check Continuity of a Function If Interval is not Given

Mathematical Consequences With the aid of the Mean Value Theorem we can now answer the questions we posed at the beginning of the section Consequence 1 If f0(x) = 0 at each point in an open interval (a;b), we can conclude that f(x) = C for some constant C for all x in the interval (a;b)DO For any $b$ in an interval as above, $f'(b)$ will never be 0, and $f'(b)$ will always be defined Why?6/7/18 · absolute maximum (5, 1/10) absolute minimum (0, 0) Given f(x) = x/(x^2 25) " on interval "0, 9 Absolute extrema can be found by evaluating the endpoints and finding any relative maximums or minimums and comparing their yvalues Evaluate end points f(0) = 0/25 = 0 => (0, 0) f(9) = 9/(9^2 25) = 9/(81 25) = 9/106 => (9, 9/106) ~~(9, 085) Find any relative

 · Using the fact f ( x) > 0 on the interval where the graph is above the x axis, and f ( x) < 0 on the interval where the graph is below the x axis we have a f ( x) > 0 for x ∈ ( − 3, − 2) ∪ ( 0, 2) ∪ ( 3, ∞) b f ( x) < 0 for x ∈ ( − ∞, − 3) ∪ ( − 2, 0) ∪ ( 2, 3) Share answered Oct 14 '16 at 311That f(x) = 0 for some x in the interval (0;Example Find where $f(x) = x^3 3x^2$ is increasing/decreasing

By the intermediate value theorem, there is some point x 0 with g(x 0) = 0, which is to say that f(x 0) − x 0 = 0, and so x 0 is a fixed point The open interval does not have the fixedpoint property The mapping f(x) = x 2 has no fixed point on the interval (0,1) The closed disc The closed interval is a special case of the closed discSo, suppose we need to find the Fourier series for the function f(x)=x defined on the interval (0,2) How can we do this since this function is not periodic?The function f(x) = 1 / x is continuous on interval (0, 1) but not uniformly continuous on It turns out that if we restrict ourselves to closed intervals both the concepts of continuity turn out to be equivalent Functions continuous on a closed interval are uniformly continuous on the same interval
