Using the graph and the second derivative test, it is found that the relative maximum on the graph of f(x) is at x = 1 .

The critical points of a function f(x) are the values of x_0 for which:

f(x_0) = 0 .

The second derivative test states that:

If $f^{\prime\prime}(x_0) 0$ , x_0

is a minimum point.If $f^{\prime\prime}(x_0) < 0$ , x_0

is a maximum point.If $f^{\prime\prime}(x_0) = 0$ , x_0

is a neither a minimum nor a maximum point.

In this problem, the critical points are: x = 0, x = 1, x = 2 .

The graph is of the first derivative. The derivative is the rate of change, thus, the second derivative is the rate of change of the first.

For each of the critical points:

At x = 0, $f^{\prime}(x)$ is increasing, thus $f^{\prime\prime}(x) 0$ and x = 0 is a minimum.At x = 1, $f^{\prime}(x)$ is decreasing thus $f^{\prime\prime}(x) < 0$ and x = 0 is a maximum.At x = 2, $f^{\prime}(x)$ is increasing, thus $f^{\prime\prime}(x) 0$ and x = 2 is a minimum.

You have relative maximum at x=1.

Step-by-step explanation:

-Note that f' is continuous and smooth everywhere. f therefore exists everywhere on the domain provided in the graph.

f' is greater than 0 when the curve is above the x-axis.

f' greater than 0 means that f is increasing there.

f' is less than 0 when the curve is below the x-axis.

f' is less than 0 means that f is decreasing there.

Since we are looking for relative maximum(s), we are looking for when the graph of f switches from increasing to decreasing. That forms something that looks like this '∩' sort of.

This means we are looking for when f' switches from positive to negative. At that switch point is where we have the relative maximum occurring at.

Looking at the graph the switch points are at x=0, x=1, and x=2.

At x=0, we have f' is less than 0 before x=0 and that f' is greater than 0 after x=0. That means f is decreasing to increasing here. There would be a relative minimum at x=0.

At x=1, we have f' is greater than 0 before x=1 and that f' is less than 0 after x=1. That means f is increasing to decreasing here. There would be a relative maximum at x=1.

At x=2, we have f' is less than 0 before x=2 and that f' is greater than 0 after x=2. That means f is decreasing to increasing here. There would be a relative minimum at x=2.

Conclusion:

* Relative minimums at x=0 and x=2

* Relative maximums at x=1
