Question

f(x)=[(x+3)/2][x^2-4x+9] I need to find its derivative using product rule , Please Help !

Answer 1

the product rule

d/dx u.v = u dv/dx +v du/dx

in your case:
u= (x+3)/2 so find du/dx
v= (x^2-4x+9) so find dv/dx

then put all those bits into the equation above and simplify..

Answer 2

du/dx = 1/2 and dv/dx = 2x-4
is this right?

Answer 3

yes
