- <em>The graph of f is a polynomial function</em>
- <em>There are two turning points, namely, x = 0 and x = -2</em>
<h2>
Explanation:</h2>
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>

Answer:
The length of the long side of the rectangle is 38 ft.
Step-by-step explanation:
If we test out all possible factors, we will see that 15 x 38 is the most fitting.
Perimeter: 15 + 15 + 38 + 38 = 106 ft.
Area: 15 x 38 = 570 square ft.
38 ft. is the measurement of the long side and 15 ft. is the measurement of the smaller side.
Put the first number on top then start adding 6+0, 8+1, 0+4, 1+1, 0+0 and the answer is 69420
