Okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0
for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4(2)ˣ
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = 4(2)⁻³
- Exponents: f(-3) = 4(1/8)
- Multiply: f(-3) = 1/2
