(a) Consider the function {(x) = 1;\" x2 _ 25. Enter the number of critical pointsfnumbers of x). :I Determine the xcoordinates of the critical points. Enter your answer as a commaseparated list of values. The order of the values does not matter. Enter DNE if x) does not have any critical points. (b) Consider the function g(x] = v\" 25 x2- Enter the number of critical pointsfnun'lbers of g(x). :l Determine the xcoordinates of the critical points. Enter your answer as a commaseparated list of values. The order of the values does not matter. Enter DNE if g[x) does not have any critical points
