If f(x)=ax+b/x and f(1)=1 and f(2)=5, what is the value of A and B?

Step-by-step explanation:

Putting x = 1

=>

Given that f(1) = 1

=>

=>  -------------------(1)

Now,

Putting x = 2

=>

Given that f(2) = 5

=>

=>

=>  ----------------(2)

Subtracting (2) from (1)

For b , Put a = 9 in equation (1)

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
