The value of ‘c’ in Rolle’s theorem for  on [-1,1]

For such questions, we should know the properties of Rolle's theorem.

To verify Lagrange’s mean value theorem, there exists at least one point c(a,b) such that

Let P(x)be a real polynomial of degree 4 having extreme values at x=1 and x=2 if  then p(4) is equal to

40 mL of 0.05M Na₂C0₃. NaHC0₃ 2H₂0 (sesquicarbonate) is titrated against 0.05 M HCL X mL of HCI is used when phenolphthalein is the indicator and y mL HCI is used when methyl orange is the indicator in two separate titrations; hence (y - x) is:
