Question

Asked Sep 23, 2019

Step 1

At x=-1 , left hand limit=-1

Right hand limit= a(-1)-b= -a-b

The function is continuous so left hand limit = right hand limit

-1 = -a - b

Or, a+b= 1

Step 2

At x=1 , left hand limit= a(1)-b=a-b

Right hand limit= 6

The function is continuous so left hand limit = right hand limit at x=1

a - b=6

Step 3

a+b=1

a-b=6

From these two equations we have to find a and b.
