Solve for y so...
3y=-2x+1479
y= -2/3x + 493
then all you do after this is replace y with f(x) so....
f(x)= -2/3x + 493
The increment in is approximately .
<h3>How to estimate an increment in
by linear approximation</h3>
The <em>linear</em> approximation is derived from definition of tangent, that is to say:
(1)
Where:
- - Slope of the function evaluated at .
- - Increment in .
- - Increment in .
The slope is found by derivatives:
(2)
If we know that and , then the increment in is:
The increment in is approximately .

You need to write this question out in algebra form first. X + x + 1 + x + 2 = 72 than you add the like terms
3x + 3 = 72 ... 3x=69 ... x=69/3 ... x=23. So we have now found x now you just add 1 to x and get 24 and you add 2 to x you will get 25.
Add 23 + 24 + 25 together you will get 72
The answer to your question is number 2
