Explanation:
Rewrite the first 2 terms in the form
# ax^n" before differentiating using the"color(blue)" power rule "# If f(x) =
# ax^n rArr f'(x) = nax^(n-1) # and
#d/dx("constant") = 0 #
# d/dx ( 1/4 x^4 - 1/2 x^3 - 9x^2 + 3x +11) #
#= 4xx1/4 x^3 - 3xx1/2 x^2 - 2xx9 x^1 +1xx 3x^0 + 0 #
#= x^3 - 3/2 x^2 - 18x + 3#
