8 0

Answer:

(cos π/4, sin π/4) or approx. (0.707, 0.707)

Step-by-step explanation:

The length of the blue ray is 1.  That's the same for any ray drawn inside the circle.

Then a = cos π/4 and b = sin π/4.

The cartesian coordinates of the point (a, b) are

(cos π/4, sin π/4) or approx. (0.707, 0.707)

Estimate and classify the critical points for the graph of the function<br> Please show work
ikadub [295]

The critical points of the function graphed are given as follows:

  • x = -1.5: Local maximum.
  • x = -1: Local minimum.

<h3>What are the critical points of a function?</h3>

The critical points of a function are the values of x for which:

f^{\prime}(x) = 0

In a graph, they are turning points, and are classified as follows:

  • Local maximum, if the functions changes from increasing to decreasing.
  • Local minimum, if the functions changes from decreasing to increasing.

Looking at the graph, the turning points are approximately:

  • x = -1.5: Local maximum.
  • x = -1: Local minimum.
