Simply plug in the value for x.
If x is equal to -18, then plug in -18 for x.
Example:
f(x) = 15 + x/5.
f(5) = 15 + 5/5.
Then solve the equation.
A function is just something that receives some value and then barfs a value out. This is an IO relationship. (Input/Output).
You said x + 2/5 = 12
It might be easier to handle if we use the decimal for 2/5.
x + 0.4 = 12
Subtract 0.4 from each side: x = 11.6
That's all there is to it. I'm sorry I can't make it
more complicated for you.
<u><em>Answer:</em></u>
<u><em>Well first we must see if they are proportional.
