state whether each relation y=f(x) describes a quadratic function or not
y=3-x^2
yes
each value of x produces a distinct value of y.

The relation y = 3 - x^2 describes a quadratic function.
To determine whether the relation y = f(x) describes a quadratic function or not, we need to examine the form of the equation.
A quadratic function is in the form y = ax^2 + bx + c, where a, b, and c are constants.
Looking at the given equation, y = 3 - x^2, we can see that it matches the form of a quadratic function. Here, the coefficient of x^2 is -1, the coefficient of x is 0, and the constant term is 3.
Therefore, the relation y = 3 - x^2 describes a quadratic function.
