# A formula for a function yequals =f(x) is f(x)equals =8 x Superscript 5 8x5.

A formula for a function yequals

=​f(x) is ​f(x)equals

=8 x Superscript 5

8x5. Find f Superscript negative 1 Baseline left parenthesis x right parenthesis

f−1(x) and identify the domain and range of f Superscript negative 1 Baseline left parenthesis x right parenthesis

f−1(x). To check the​ answer, determine whether f left parenthesis f Superscript negative 1 Baseline left parenthesis x right parenthesis right parenthesis equals f Superscript negative 1 Baseline left parenthesis f left parenthesis x right parenthesis right parenthesis equals x

ff−1(x)=f−1(f(x))=x.

f Superscript negative 1 Baseline left parenthesis x right parenthesis

f−1(x)equals

=

nothing
