The x-intercepts are (-2, 0) and (2, 0), the minimum is at (0, -3), and the line of symmetry is x = 0 if the equation of the parabola is y = x²—4
<h3>What is a parabola?</h3>
It is defined as the graph of a quadratic function that has something bowl-shaped.
Here the graph or equation is not given:
So we are assuming the equation for the parabola is:
y = x²—4
If we plot the graph of the parabola, we can say:
- The x-intercepts are (-2, 0) and (2, 0)
- The minimum is at (0, -3)
- The line of symmetry is x = 0
Thus, the x-intercepts are (-2, 0) and (2, 0), the minimum is at (0, -3), and the line of symmetry is x = 0 if the equation of the parabola is y = x²—4

Answer: 
Step-by-step explanation:
According to the product rule of derivatives.

The given function : 
here ,
and 
Differentiate both sides with respect to x, we get
and 
![[\because \dfrac{d(ax)}{dx}=a\ , \dfrac{d(a)}{dx}=0 \ \&\ \ \dfrac{d(x^n)}{dx}=nx^{n-1}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Bd%28ax%29%7D%7Bdx%7D%3Da%5C%20%2C%20%5Cdfrac%7Bd%28a%29%7D%7Bdx%7D%3D0%20%5C%20%5C%26%5C%20%5C%20%5Cdfrac%7Bd%28x%5En%29%7D%7Bdx%7D%3Dnx%5E%7Bn-1%7D%5D)
Then, Tge derivative of withe respect to x will be :




Hence, the derivative of the function is
.
Answer:
3420°
Step-by-step explanation:
The sum of angle measures of an n-gon is ...
angle total = (n-2)×180°
For n = 21, the angle total is ...
21-gon total = (21 -2)×180° = 3420°
