The one with the red x

(a) Consider the function f(x) = (6x + 1)(5x + 7). Enter the number of critical pointsumbers of f(x). 1 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 f(x) does not have any critical points. 0 X (b) Consider the function g(x) = ox + 1 5x + 7 Enter the number of critical pointsumbers of g(x). 0 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 g(x) does not have any critical points. DNE
