The number of fish swimming upstream to spawn is approximated by the function given below, where x represents the temperature of the water in degrees celsius. find the water temperature that produces the maximum number of fish swimming upstream. f(x)= -x^3 + 3x^2 + 189x + 5143, 4 ≤ x ≤ 18 the maximum number of fish swimming upstream will occur when the water is degres celslus (round to the nearest degree as needed.)
