Assalam o Alaikum Wa Rehmatullahi Wa Barakaatuhu dear sir, shouldn't the answer be -8 instead of a +8, in Q1 (c).
@FarhanAhmed-999 Says:
In Q8(b) 3(-1)2square should equals to 3 because under the bracket minus should be ignore so why sir did 3(-1)2square equals to -3 ? and the answer should be -7, right ?

In Q10, we are supposed to find the stationary points on the curve and we've learnt that at stationary point dy/dx =0 so shouldn't we find the stationary points using the equation y=f(x) instead of f`(x). Don't we use f`(x) for determining the nature of the stationary points 🤔
