SOLUTION: Take a look at the table below and write out an equation for f(x). I put ":" and commas to stipulate where there would be a line to box them in...like a table etc. x: -2, -1,

Question 173602: Take a look at the table below and write out an equation for f(x). I put ":" and commas to stipulate where there would be a line to box them in...like a table etc.
x: -2, -1, 0, 1, 2
f(x): -1, 1, 3, 5, 7

Answer by 303795(602) (Show Source): You can put this solution on YOUR website!
The x's are going up by 1 and f(x) goes up by 2. This means that part of the rule will be
f(x)=2x
Test this rule against the numbers in your table.
If x=2 then 2x=4 but f(x) = 7 which is 3 more than the current part of the rule gives so change the rule to
f(x)=2x+3
Check this rule against the numbers in your table. It should work for all x values now.
