f(x)=3x
f left parenthesis x right parenthesis equals 3 Superscript x

f(x)=−2x
f left parenthesis x right parenthesis equals negative 2 Superscript x

f(x)=2x+1
f left parenthesis x right parenthesis equals 2 Superscript x plus 1

f(x)=(12)x
f left parenthesis x right parenthesis equals left parenthesis one half right parenthesis Superscript x

f(x)=2x−1
f left parenthesis x right parenthesis equals 2 Superscript x Baseline minus 1

Answer 1

The functions that have the same f(x)-intercept as f(x) = 2x are:

1. f(x) = -2x (f left parenthesis x right parenthesis equals negative 2 Superscript x)
2. f(x) = 2x - 1 (f left parenthesis x right parenthesis equals 2 Superscript x Baseline minus 1)
