Hey, I need your help! I have an input output table that I need the function rule for. The table is like this:
Input: 0 Output: 25
Input: 100 Output: 35
Input: 200 Output: 45
Input: 300 Output: 55
Input: 400 Output: 65
PLEASE I NEED YOUR HELP!!! Thanks!

  1. try linear
    y = m x + b
    35 = m (100) + b
    65 = m(400) + b
    -----------------
    -30 = -300 m
    m = 1/10

    35 = 10 + b
    b = 25

    so I think
    y = 0.1 x + 25
    or
    10 y = x + 250
    try that
