A.
x ≤ 4
B.
0 ≤ x ≤ 4
C.
all real numbers
D.
x ≥ 0
The domain of the function represented by the given graph is option B: 0 ≤ x ≤ 4.
A parabola is a U-shaped curve, and in this case, it opens upwards since the coefficient of the squared term is positive. As the parabola is symmetric, it will extend indefinitely in both directions. Therefore, the parabola includes all real numbers.
However, the domain of the function represented by this graph is limited. The function is defined for all x-values along the parabola. Still, it may not be defined for x-values that lie beyond the points where the parabola intersects the x-axis.
Since the points of intersection are (0, 0) and (4, 0), we can conclude that the function is only defined for x-values between 0 and 4, inclusive. This is because any x-value less than 0 or greater than 4 would lie outside the range of the parabola, and the function would not be defined at those points.
So, the correct answer is option (b).

Answer: x = 5
You can pick any number you want, as long as it's not zero. The equation x = 5 has all points on this line that have an x coordinate of 5. The y coordinate can be anything you want
Example points on this line are: (5,1) and (5,2)
Note: this is a vertical line with the slope undefined. There is no y intercept. This is not a function because it fails the vertical line test.
