Elimination is where you aline two equations with the varibles in the same place and the second equation substracts the first equation. Important to know that in the second equation all varibles and constant or y - intercepts are negative. Now with this just start with the first two equations, 5x + 2y -3z = 10 and 2x - 2y + 4z = 6.

5x + 2y - 3z = 10

- 2x + 2y - 4z = -6

3x + 4y - 7z = 4

Do the same thing with the last equation.

3x + 4y - 7z = 4

-x + y - 2z = -3

2x + 5y -9z = 1

Please tell me if I got it wrong, but from what I concluded there's no solution.

We are asked to determine what happens to the values of $f(x)$ as $x$ approaches $2$ using values of $x$ less than $2$ AND using values of $x$ greater than $2$ .

<span>Observe from the graph that as </span> $x$ approaches $2$ from the left or the right, the values of $f(x)$ increase without bound.

Therefore, we know the following.

$\text{lim} \ f(x) = +\infty}$
