Originally Posted by skeske1234 find the derivative dy/dx a) y=(x+1)/(x-1) y'=1(x-1)^-1 ...?? use the quotient rule b) y=3/(x+2) y'=3(x+2)^-1 ...? correction ... , it's not y' yet ... you still need to use the power rule and take the derivative. c) y=sqrt(3x+2) y'=(3x+2)^(0.5) ...? no ... , it's not y' yet ... use the chain rule. ...
