Okay so, f(x) is another way of writing y.
If the problem were to give you an x value you would put it in the x spot.
For example:
f(x) = 1/2x - 7
is the same thing as y = 1/2x - 7
If the problem were to say: "Solve for y, if x = 2" your problem would look like this
f(2) = 1/2(2) + 7
Now, multiply 1/2 by 2, and you get 1. Now the equation is:
f(2) = 1 + 7
So add 1 and 7 = 8
so that would be f(2) = 8
And your final answer would be y = 8

Answer:
The bottom left system of equations has no solutions.
Step-by-step explanation:
A solution to the system of equations is a point where the graphs of equations intersect, because the intersection point represents a point that is common to both equations; Therefore, a system that has no solutions, will have graphs that will never intersect.
Now, looking at the 4 graphs given, we see that the upper-left graph represents lines which intersect; therefore, this system has a solution.
The upper-right graph represents only one equation and not a system—it could well be that the red line hides another line that is exactly beneath it, in which case the system would have infinitely many solutions.
The bottom-left graph represents lines that are parallel—they are never going to meet; therefore, this system has no solutions.
The bottom-right graph represents lines that have a point of intersect, and therefore, have a solution.
Thus only the bottom-right graph has no solutions.
