Question Use the Second Derivative Test to find the location of all local extrema in the interval \( (-21,-9) \) for the function given below. \[ f(x)=\frac{7(x-1)^{2}}{x+9} \] If there is more than one local maxima or local minima, write each value of \( x \) separated by a comma. If a local maxima or local minima does not occur on the function, enter \( \varnothing \) in the appropriate box. Answer should be exact.
