Question

Send help haha

Use the drop-down menus to identify the domain and range of each function below.

The drop-down menu has the same options for every one of them.

Please answer correctly ASAP ^

Answer 1

Domain: input values (x-values)

Range: output values (y-values)

Absolute value: remove negative sign → output becomes positive
eg. |-2| = 2

Squaring a number → output is always positive

`a(x)=3|x|`

Domain = all real numbers

Range = all positive numbers and zero

`b(x)=3x^2`

Domain = all real numbers

Range = all positive numbers and zero
