Question

If f(x)= ax + B, and f ={(1, 1), (2, 3), (3, 5), (4,7)}, then the values of a, b are​

Answer 1

Answer

Correct option is

A

2,−1

f(1)=α+β=1

f(2)=α×2+β=3

∴α=2, β=−1

Checking for rest of values using above α and β also satisfies the function's input and output.

Thus option A is correct.
