Question

How do i solve this?
Write a rule for the function.


Input,x 0 1 2 3
Output,y 3 5 7 9

Answer 1

Assistance needed.

Answer 2

what's the relationship between the input and output?
0->3 (add 3+0)
1->5 (add 3+1)
2->7 (add 3+2)
3->9 (add 3+3)
so...

Answer 3

so you're doubling the original number (input) and adding three

how would you express the relationship between the input and output algebraically?

Answer 4

3 - 0 = 3 for x = 0
5 - 1 = 4 for x = 1
7 - 2 = 5 for x = 2
9 - 3 = 6 for x = 3

y = x + 3 + x = 2 x + 3
