The graph of the function
f
(
1
28
x
)
\displaystyle {f{{\left(\frac{{1}}{{28}}{x}\right)}}}
f
(
28
1
x
)
can be obtained from the graph of
y
=
f
(
x
)
\displaystyle {y}={f{{\left({x}\right)}}}
y
=
f
(
x
)
by one of the following actions:
vertically compressing the graph of
f
(
x
)
\displaystyle {f{{\left({x}\right)}}}
f
(
x
)
by a factor 1/28
horizontally compressing the graph of
f
(
x
)
\displaystyle {f{{\left({x}\right)}}}
f
(
x
)
by a factor 1/28
vertically stretching the graph of
f
(
x
)
\displaystyle {f{{\left({x}\right)}}}
f
(
x
)
by a factor 28
horizontally stretching the graph of
f
(
x
)
\displaystyle {f{{\left({x}\right)}}}
f
(
x
)
by a factor 28
