Graph of f f : Graph of f′ f ′: DO : Try to follow the process (above) to work this problem before looking at the solution below. Solution: f′(x) = 3x2 − 6x = 3x(x − 2) f ′ ( x) = 3 x 2 − 6 x = 3 x ( x − 2) Since f′ f ′ is always defined, the critical numbers occur only when f′ = 0 f ′ = 0, i.e., at c = 0 c = 0 and c = 2 ...
To determine the intervals where a graph is increasing and decreasing: break graph into intervals in terms of T, using only round parenthesis and determine if the graph is getting higher or lower in the interval. First interval: goes from the left edge of the graph which has an T− K N 𝑖 J𝑎 P of T= −∞ To find the intervals of increase and decrease on a graphing calculator, you need to first find the x-intercepts of the function. This can be done using the "zero" or "root" function on the calculator.

it continues to decrease until about 1.2; it then increases from there, past x = 2; Without exact analysis we cannot pinpoint where the curve turns from decreasing to increasing, so let us just say: Within the interval [−1,2]: the curve decreases in the interval [−1, approx 1.2] the curve increases in the interval [approx 1.2, 2]
f ′ can only change sign at a critical number. The reason is simple. If f ′ ( x) is continuous and it changes sign, then it has to pass through 0 on its way from negative to positive (or vice versa ). That's the Intermediate Value Theorem. If f ′ ( x) is not continuous where it changes sign, then that is a point where f ′ ( x) doesn't ...

If you take the left and right Riemann Sum and then average the two, you'll end up with a new sum, which is identical to the one gotten by the Trapezoidal Rule. (In fact, according to the Trapezoidal Rule, you take the left and right Riemann Sum and average the two.) This sum is more accurate than either of the two Sums mentioned in the article.Then: divide the decrease by the original number and multiply the answer by 100. % Decrease = Decrease ÷ Original Number × 100. If your answer is a negative number, then this is a percentage increase. If you wish to calculate the percentage increase or decrease of several numbers then we recommend using the first formula.
