Question

(1, 5), (2, 9), (3, 13), (4, 17)

Which of the following functions best represents the rule that the calculator uses to display the outputs?

Answer 1

I belive the function is y=4x+1, it works with every set

Answer 2

The function is y=4x+1

5 = 4(1) + 1
5 = 4 + 1
5 = 5

9 = 4(2) + 1
9 = 8 + 1
9 = 9

13 = 4(3) + 1
13 = 12 + 1
13 = 13

17 = 4(4) + 1
17 = 16 + 1
17 = 17

Hope this helps!
