2. 6x - 9
3. -10y + 29
4. 4x - 3
Step-by-step explanation:
i dont know how to explain. Sorry, i just learn about this today. I have the same exactly questions and here is the answer.
2 -> 7; but 7 = 2 * 2 + 3;
3 -> 9; but, 9 = 3 *2 + 3;
4 -> 11; but, 11 = 4 * 2 + 3;
5 -> 13; but, 13 = 5 * 2 + 3;
The rule is : ( your number ) * 2 + 3;
The function rule is f( x ) = 2x + 3.
