- How do you find the limit of #\lim _ { x \rightarrow 3} 5\cdot \frac { \sqrt { x + 1} - 2} { x - 3}#?
- Differentiate #y=(x+1)^(1/2)+(x+1)^(-1/2)# using quotient formula?
- How do you differentiate #f(x)=(x^3-3x^2-3x-6)/((x-6)(x-1)# using the quotient rule?
- Differentiate #y=f(x)=1/sqrt(1-x)# using the definition of derivative #(dy)/(dx)=lim_(h->0)(f(x+h)-f(x))/h#?
- How do you find the difference quotient of #f#, that is, find #((f(x+h)-f(x))/h)#, #h != 0# for #f(x)=x^2-5x+7#?
