Marge draws this graph of the exponential function f(x)=12(5)x−3

Question

. 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

The function \( f(x) = 12(5)^{x-3} \) is an exponential function. Exponential functions are defined for all real numbers.

Therefore, the domain of Marge’s function can be described as:

\[ -\infty < x < \infty \]

So the inequality to complete is:

\[ -\infty < x < \infty \]
