# If the following

Answer :

Given information: f(x) is differentiable at x = 2

Since the function is differentiable therefore it should be continuous at x =2

Applying the continuity condition,   Also since it is differentiable,

Left hand derivative = Right hand derivative    Since b = 4 – 2a a=4

Also b=4–2a

b = 4–2×4

b = –4.

Hence the values of a and b are 4 and –4 respectively.
