Question

Use the image to answer the question.

A curve with arrows at both the ends facing upward is plotted on a coordinate plane with x and y axes ranging from negative 10 to 10 in unit increments.
The equation of the curve is f left parenthesis x right parenthesis equals one half times left parenthesis 5 right parenthesis superscript x baseline minus 3. The coordinates through which the curve passes through are left parenthesis negative 10 comma negative 3 right parenthesis, left parenthesis negative 2 comma negative 3 right parenthesis, left parenthesis 0 comma negative 2.5 right parenthesis, left parenthesis 1 comma 0 right parenthesis, and left parenthesis 2 comma 9 right parenthesis. Points are approximate.


Marge draws this graph of the exponential function f(x)=1/2(5)^(x)−3. Complete the inequality to show the domain of Marge’s function.

(1 point)
The domain of Marge’s function can be described as −∞<x< [?] .

Answer 1

∞

So the domain is all real numbers: -∞ < x < ∞.
