2. Given that f(3)=1,g(3)=-9,f_1(3)=-1,g_1(3)=7 Calculate (f*g)_1(3)=? Calculate (f/g)_1(3)=?
sorry, what's f_1(3)? I don't get the underscore/underline.
Calculate (f*g)_1(3)=1*-9 Calculate (f/g)_1(3)=1/7
f_1(3)/g_1(3)=-1/7 F_(3)*g_(3)=-1*7=-7
f(3)=1, g(3)=-9, f'(3)=-1, g'(3)=7 Calculate (f*g)'= -1 x 7 = -1/7 Calculate (f/g)'= 3/-9 x 7 = -27/7 I'm not sure about this sorry, I'm not use to the way that you have learnt it with the _ , it's too confusing for me.
