Question

Identify the domain of the exponential function shown in the following graph: (2 points) Exponential graph starting at point 0, 30000 and approaching the x axis as it moves left to right. Select one: a. all real numbers b. x ≥ 0 c. 0 ≤ x ≤ 30,000 d. 7 ≤ x ≤ 30,000

Answer 1

b. x>=0
You don't say it terminates but goes to infinity, therefore all values of x>=0 is the domain

Answer 2

Answer: b.
`x\geq 0` , where x is the positive real numbers.

Explanation:

We Know that, The Set of all Possible values of independent variable is called Domain of the function.

Since, Exponential graph starting at point (0, 30000),

Thus, the initial value of value of independent variable is 0.

Also, The given exponential function is approaching the x axis as it moves left to right.

Therefore, The Domain must contain the all positive real numbers.

Thus, the Domain of the given function is
`x\geq 0` , where x is the positive real numbers.

Therefore, Option b is correct.
