The following function is given
f(x)=x^2+0.1x-6 |x|, -3≤x≤3
a) What is its derivative f′(x)for x>0?
b)What is the derivative f′(x)for x<0?
c) Give the x-value where the derivative is not defined
d) List the xcoordinate of all the critical points of f(x)in the format (x1,x2,...,xn), for example (1,2,3).
