Use the function to answer the question.

f : x --> 3 - x

f : x --> 3 -x

what is the value of f(-4)

D. One side of the equation is a quadratic expression, and the other side of the equation is a quadratic expression.

Step-by-step explanation:

Knowing that she got an infinite number of points in the resolution, indicate us that both sides of the equation have a similar expression, that is, both are linear,  both are quadratic, et cetera. Because, in this case, the two terms overlap each other giving infinite solutions. In any other case, for example, one term is constant and the other is quadratic, the solution (if exist) gives finite points. In the example that could be one or two points, depending on the specific case.
