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!

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 
If input is 100 what is output number?

input 3 , 5 , 10 , 50 , 100
output 9 ,15 , 30 ,150 , 300 
what do you think about math

input and output of 1,2,3,4,5,6,7,8,9

What is the function rule for 0,31 1,27 2,23 3,19

Same question for my homework! Someone please answer, I'm having a hard time.

my output number is 7 34 45 56 i need the input number
