What is the Domain and Range of #f(t) = 20#?

Answer 1

Savannah Anderson

The domain is the set of all real numbers: #{RR}#

The range is: #{20}#

There are no exclusions for the value of #t#.

For every values of #t# the function's result is #20#

The domain of ( f(t) = 20 ) is all real numbers, denoted as ( (-\infty, \infty) ), because there are no restrictions on the input ( t ). The range of ( f(t) = 20 ) is a single value, which is 20, because the function output is constant regardless of the input ( t ). Therefore, the range is ( {20} ).
