Question

Which of the following could be an example of a function with a domain (-♾️,♾️) and a range (-♾️,2)? Check all that apply

Answer 1

Given

The expression are given

`\begin{gathered} y=-(3)^x+2 \\ y=-(3)^x-2 \\ y=-(0.25)^x+2 \\ y=-(0.25)^x-2 \end{gathered}`

Step-by-step explanation

The domain is the set of values of x for which the function is defined.

The range is the set of values of y for which the function is defined.

For the options A and C ,

The domain is (-♾,♾) .

The range is (-♾,2)

Answer

Hence the correct options are

A ,C
