Question

f(x)=3*2^x graph

Give range and domain of function

Answer 1

Hi Ashley, the domain of the function is (-∞, ∞), or any value of x will be valid.

 

The range of the function is (0, ∞), or as x goes negative, y approaches 0 and as x gets large, y goes to infinity.

 

Questions?

Answer 2

This is a fairly basic exponential function (no constant added) so x may be any Real number and y will be any positive number.

 

There must be many examples of graphs of this type in your textbook (or whatever they teach from these days).

 

You can also Google 'exponential function graphs'.
