What is the range of the function #f(x) = 5 - 8x #?

Answer 1

See a solution process below:

First, because there are no restrictions on the value #x# can be, then the domain of the function is the set of Real numbers: #{RR}#

The function is a linear transformation of #x# and therefore the domain is also the set of Real numbers: #{RR}#

Here's a graph of the function for you to see that domain is #RR#.
