f left parenthesis x right parenthesis equals 2 Superscript x Baseline minus 1
f(x)=3x
f left parenthesis x right parenthesis equals 3 Superscript x
f(x)=(12)x
f left parenthesis x right parenthesis equals left parenthesis one half right parenthesis Superscript x
f(x)=−2x
f left parenthesis x right parenthesis equals negative 2 Superscript x
f(x)=2x+1
The functions that have the same x-intercept as f(x)=2x are:
1. f(x)=2x-1
2. f(x)=-2x
These functions shift the graph of f(x)=2x by a vertical translation to the left or right with the same x-intercept.
