{a} Consider the function f(x) = [8x + 3][7x + 1). Enter the number of critical pointsfnumbers of f(x). :i Determine the X-coordinates of the critical points. Enter your answer as a comma-separated list of values. The order of the values does not matter. Enter DNE if x) does not have any critical points. 8x+3 b Consider thefunction x 2. ( ) g( ) 7\" 1 Enter the number of critical pointsfnumbers of g(x}. :i Determine the x-coordinates of the critical points. Enter your answer as a comma-separated list of values. The order of the values does not matter. Enter DNE if gfx) does not have any critical points
