- <em>The graph of f is a polynomial function</em>
- <em>There are two turning points, namely, x = 0 and x = -2</em>
A polynomial function in one variable is given by the form:
Since you haven't provided any expression, I'll choose the following function:
So this is indeed a polynomial function. A turning point is an x-value where we have either a local maximum or local minimum. So we need to take the derivative of this functions:
Conclusion:
- <em>The graph of f is a polynomial function</em>
- <em>There are two turning points, namely, x = 0 and x = -2</em>

Using a trigonometric identity, it is found that the values of the cosine and the tangent of the angle are given by:
The identity that relates the sine squared and the cosine squared of the angle, as follows:
In this problem, we have that the sine is given by:
Hence, applying the identity, the cosine is given as follows:
The tangent is given by the sine divided by the cosine, hence:
