How do you find the composition of functions in Chapter 1?
Answer (1)
In NCERT Class 12 Maths Chapter 1, the composition of functions means applying one function to the result of another. If we have two functions f(x) and g(x), their composition is written as (f o g)(x), which means f(g(x)).
Steps to find composition:
1. First, find g(x) (solve for x in g ).
2. Substitute g(x) into f(x).
3. Simplify the expression.
For example, if f(x)=x2 and g(x)=x+1, then:
(f o g)(x)=f(g(x))=f(x+1)=(x+1)2
