Question

Linear function f(x) = ax + b is an identity
function if

a) a=0, b=1
b) a=1, b=0
c) a=1, b=1
d) a=0, b=0​

Answer 1

Step-by-step explanation:

i think your can be

A. a=0,b=1

hope it helps......

Answer 2

The correct answer is a=0, b=1.

Given: Linear function f(x) = ax + b.

To Find: Value of a and b.

Solution:

Identity function: a function (such as f(x)) that is everywhere equal in value to the value of its independent variable (such as x).

So in this the function f(x) = ax + b.

For the function to be independent of x.

ax = 0

a = 0

And b is independent of x, so it can contain any value. But for this question b = 1.

Hence, the value of a = 0, b = 1.
