Q1. Let f(x)=√x(1+sin(π/x)), x>0. Determine whether it is possible to extend f to a continuous function ˜ f


Q2. Let g(x)=(x2+1)sinx.

(a) Without using differentiability of g, explain why g is continuous.

(b) Explain why g is differentiable, and then find the derivative of g.

Q3.Let f(x)=∣x+3∣3/2/ ∣x−4∣ .

(a) Write f as a case-defined function.

(b) Compute the derivative of f. You should determine when you can use the formulas of derivatives and rules of differentiation and when you should apply the definition of derivative.
