Which value is an input of the function
2 answers:
Answer:
D. 4
Step-by-step explanation:
We have been given graph of a function. We are asked to choose the value, which is input of the given function.
We know that input of a function is value of the independent variable. Upon looking at our given graph, we can see that x is independent variable.
All the values in domain of our a function will be input values.
We can see that domain of our given function is .
Our function is defined for x values that are greater than or equal to 1, so first three options are not correct choice.
Since our function is defined at , therefore, 4 is an input of the given function.

The distance from the center to where the foci are located exists 8 units.
<h3>How to determine the distance from the center?</h3>The formula associated with the focus of an ellipse exists given as;
c² = a² − b²
Where c exists the distance from the focus to the center.
a exists the distance from the center to a vertex,
the major axis exists 10 units.
b exists the distance from the center to a co-vertex, the minor axis exists 6 units
c² = a² − b²
c² = 10² - 6²
c² = 100 - 36
c² = 64
c = 8
Therefore, the distance from the center to where the foci are located exists 8 units.
