Question

4. If {(2,8) (6,b) } represent the value of a and b. find identity function, find a and b​

Answer 1

Answer:

$\rm \: a = 8 \: \: and \: \: b = 6$

Step-by-step explanation:

$\rm \{(a,8) (6,b) \}$

We know that :-

$\rm f(x) = x$

$\rm Let \: \: f(x) = 8 \: and \: x = a$

$\rm \therefore \: 8 = a$

$\rm or \: \: a = 8$

$\rm Let \: \: f(x) = 6 \: and \: x = b$

$\rm \therefore \: 6= b$

$\rm or \: \: 6= b$
