What is the domain and range of #f(x) = 3x + 1#?

1 Answer

Answer:

Domain: #-oo<"x"<+oo#
Range: #-oo<"f(x)"<+oo#

Explanation:

This is a linear function. A linear function extends from #-oo# to #+oo#, so that all values of x is allowed and the value of f(x) also includes the set of all real numbers. For any real value of x, there corresponds a unique real value of f(x).

Kindly see the graph of #f(x)=3x+1#

graph{y=3x+1[-20,20,-10,10]}

God bless....I hope the explanation is useful.
