Find the domain and range of the following function f(x) = 51x - 21+ 4

Serjik [45]

Answer:

All linear functions have domain and range all real numbers.*

*Did you really mean to write f(x)=5x-21+4

Seems weird the -21+4 thing but okay...

Step-by-step explanation:

Looks like you have a line

f(x)=51x-17

All linear functions have domain and range all real numbers.

The only time a line will not be a function is if you have a vertical line.
