8-26.

The functions

*f*(*x*) = 2,^{x}*f*(*x*) = 2 · 2, and^{x}*f*(*x*) =· 2 all have the same multiplier.^{x}*8-26 HW eTool*(Desmos). Homework Help ✎What is the multiplier for these functions? Make an

*x*→*f*(*x*) table for each of the functions, using integer values of*x*for*x*= −3 to*x*= 5. How can you use the tables to determine the multiplier?On the same set of axes, sketch the three functions. Describe the similarities and differences among the graphs.

For example, compute *f*(1) and *f*(2). What number do you need to multiply *f*(1) by to get *f*(2)?

Compare the general shapes, intercepts, asymptotes, and growth rates.
