Question

For the table below, determine the function rule, and find each of the missing y-values.




Function Rule: ?


x y



1 4
3 6
4 7
5 ?
7 10
10 ?

Answer 1

well you can see that as x increases from 1 to 3 2 places
y increases from 4 to 6 2 places

so the equation looks like y = x + b

you just need to add( or subtract) a number

using x = 3 and y = 6

y = 3 + b

whats the value for b

does it work for x = 1 and y = 4

4 = 1 + b

then you have your equation and can dind the missing values.
