Consider a function f (x) = x 3 + 3x 2 – 45x + 9. To find intervals of increase and decrease, you need to differentiate them concerning x. After differentiating, you will get the first derivative as f’ (x). Therefore, f’ (x) = 3x 2 + 6x – 45.
To answer this, use the following steps: Identify the initial value and the final value. Input the values into the formula. Subtract the initial value from the final value, then divide the result by the absolute value of the initial value. Multiply the result by 100. The answer is the percent increase.1. So this is a question about the sign of the derivative. Recall that if f′ > f ′ > 0, then f is increasing whereas if f′ f ′ < < 0, then f is decreasing.

Increasing and Decreasing Functions. Increasing means places on the graph where the slope is positive. The formal definition of an increasing interval is: an open interval on the x axis of (a, d) where every b, c ∈ (a, d) with b < c has f(b) ≤ f(c). A interval is said to be strictly increasing if f(b) < f(c) is substituted into the definition.

1. So im supposed to find the interval of decrease and increase here. Ive gotten up to taking the derivative which is −4x(x2 − 1) − 4 x ( x 2 − 1) and then setting it to 0 i got (-1,0,1) Im lost at what to do now? Im supposed to take it for this below: f(x) = 7 + 2x2 −x4 f ( x) = 7 + 2 x 2 − x 4. You really need to slow down.

Explanation: To find the an increasing or decreasing interval, we need to find out if the first derivative is positive or negative on the given interval. So, find by decreasing each exponent by one and multiplying by the original number.1. So this is a question about the sign of the derivative. Recall that if f′ > f ′ > 0, then f is increasing whereas if f′ f ′ < < 0, then f is decreasing.
