Whenever your function changes from decreasing to increasing, or when your first derivative changes from negative to positive, you have a relative minimum (and vice versa for relative maximums). This is true for x = -1 and x = 1, so both of them are relative minimums. Want to learn more about increasing/decreasing intervals and differential calculus? Check out this video. Example 1 Let's find the intervals where f ( x) = x 3 + 3 x 2 − 9 x + 7 is increasing or decreasing.

A line with a positive slope slants upward from left to right as in Figure \(\PageIndex{5}\)(a). For a decreasing ...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 ... When thinking about a spring with amplitude decreasing over time, it is tempting to use the simplest tool for the job – a lin ear function. But if we attempt to model the amplitude with a decreasing linear function, such as \(A(t)=10-t\), we quickly see the problem when we graph the equation \(f(t)=(10-t)\sin (4t)\).Step 1: Let's try to identify where the function is increasing, decreasing, or constant in one sweep.
