Determine whether the following graph represents a function

A graph may or may not represent a function depending on the relationship between the x and y values of the graph.

The given graph does not represent a function

From the graph, we observe that;

The same value of x points to the different values of y.

For instance:

When x = -6, the values of y are 3 and -3.

This is a many-to-one relation.

And a many-to-one relation does not represent a function.

Also, from the graph; there are several other values of x, that point to multiple values of y

Hence, the graph does not represent a function.

No, it is not a function

Why not? Because the graph fails the vertical line test. It is possible to draw a single vertical line through more than one point on the graph. For instance, we can draw a vertical line through x = 1 on the x axis, and this vertical line crosses the curve at two different points.

A function is only possible if any input x leads to exactly one y output.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

sorry man i accidentally pressed yes my bad
