Answer» Given : f(x) = 3x - 2 One - one proof Let x and y belongs to NSo, if f(x) = f(y) we will show x = y 3x - 2 = 3y - 2 3x = 3y x = y so f is one one. Now, we it is not onto Use hint let f(x) = 2 So, 3x - 2 = 2 So, 3x = 4 x = 4/3 But the set is only restricted to N set and 4/3 is from rational set so we can't get 2 using N set so it not onto |

how do you do substitution |
|
Answer» Substitution is process to solve equation. For example, consider two equations2x + y = 4 ....(1) x + y = 1 .... (2) We will use substitution process, so using eq (2) we can written as y = 1 - x, now substitute this in eq (1) 2x + 1 - x = 4x = 3 Therefore y = 1 - x = 1 - 3 = - 2. So, we saw an application of substitution |
