Class 11MathematicsRelations and Functions

Let f(x) = x2 and g(x) = 3x + 2 be two real functions. Then, find:

(i) (f + g)(x) 

(ii) (f - g)(x) 

(iii) (fg)(x) 

(iv) (f/g)(x)

Verified Answer

(i) f(x) + g(x) = x2 + (3x + 2) = x2 + 3x + 2

(ii) f(x) - g(x) = x2 - (3x + 2) = x2 - 3x - 2

(iii) f(x) · g(x) = x2(3x + 2) = 3x3 + 2x2

(iv) f(x)/g(x) = x2/3x + 2
