If the function f (x) given by

is continuous at x =1, find the values of a and b.

Answer :

To Find: Find the value of a and b?

For 3ax - b

where f(x) =3ax + b , then


For 5ax - 2b

where f(x) =5ax - 2b , then


Now, It is given that



3a + b=11

5a - 2b=11

Solve by elimination method

Multiply by 2 in equation (i) and Add with equation (ii)

6a + 2b=22

5a - 2b=11




putting the value of a in equation (i)

3(3) + b=11

9 + b=11

b=11 - 9


Hence, The value of a = 3 and b= 2
