Question

function is defined by f(x) = 2 x - 5. Then f ( 7 ) is :

a) 19 b) 14 c) 9 d) None​

Answer 1

Explanation:

Let f : A→ B and g : B → C be the given functions such that gof is onto. Then g is onto. ... (iii) If f : X → Y, g : Y → Z and h : Z → S are functions, then. h o (g o f) ... A4 = {4, 9, 14, 19, 24, ...}.
