Step-by-step explanation:
Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Answer:
the area of the circle is 4π
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
The area of the circle = πr^2
where
diameter = 4
So radius = diameter ÷ 2
= 4 ÷ 2
= 2
Now the area of the circle is
= π × 2^2
= 4π
hence, the area of the circle is 4π
