differentiate using gf1-g-f/g2
The answer is 4 but I dont understand how my professor got to it? Please how work so I can perhaps understand
f(x) = [4x^2 + 3] / x using the Quotient Rule, we have
f '(x) = [x * ( 8x) - 1 *(4x^2 + 3) ] / x^2 =
[ 8x^2 - 4x^2 - 3 ] / x^2 =
[ 4x^2 - 3 ] / x^2 =
4 - 3/x^2
