Lim((f(x+h)-f(x)))/h= lim(((x+h)2 -x2)/h)=lim((h2 +2xh)/h) as h tends to 0 the limit becomes 2x
a) f'(x)=2x-2-12x1/2B)f'(x)=2+6x-3/2c)f'(4)=0d) local minimum
There are two parts to this expression, the coefficients and the powers of x, and they can be addressed separately.It's important to remember the rules of indices - am x an = am...
