In the x-y plane, the point (3,1) lies on the graph of the function g. if g(x) = a - 2 x^2, where a is a constant, what is the value of a ?

The points on the graph of a function are all of the form

In fact, the graph is composed by all points such that y is the image of x, as written above.

So, if lies on graph, it means that .

Since we know the expression for , we can plug the values:

We can solve for by adding 18 to both sides to get .

So, the expression for the function is
