Use the geometric series f(x)equalsStartFraction 1 Over 1 minus x EndFraction equalsSummation from k equals 0 to infinity x Superscript k, for StartAbsoluteValue x EndAbsoluteValueless than1, to find the power series representation for the following function (centered at 0). Give the interval of convergence of the new series. f(7x)equalsStartFraction 1 Over 1 minus 7 x EndFraction.

can you put the picture up?
