Identify the domain of the exponential function shown in the following graph: exponential graph starting at point 0, 3 and approaching the x axis as it moves left to right. all real numbers x ≥ 0 0 ≤ x ≤ 30,000 7 ≤ x ≤ 30,000

the domain of the given exponential function is:

x ≥ 0   or [0,∞)

step-by-step explanation:

the domain of a function is the set of all the values at which the function is well defined i.e. the function exist there.

                                            or

it is the set of all the possible x-values( value of independent variable) at which the output is the real number.

now here we are given:

exponential graph starting at point 0, 3 and approaching the x axis as it moves left to right.

this means that the function starts taking it's value from x=0 as it is the starting point and there is no limit to the end of the interval this means that the function is defined for all the real numbers greater than and equal to zero.

              hence, the domain is:

                x ≥ 0   ( which is: [0,∞) )

the correct option is 1.

step-by-step explanation:

from the given information is clear that graph starting at point (0,3) and approaching the x axis as it moves left to right.

the y-intercept of the exponential function is (0,3) and graph of approaches towards right. it means function is defined for all positive values of x.

domain is the set of all possible inputs for which the function is defined.

the given function is defined for all positive values of x. so, the domain of the function is all positive real number.

interval notation of domain is .

therefore option 1 is correct.
