Determine whether the equation defines y as a function of x.
y=-17
Hint: Where is the x?
To determine whether the equation defines y as a function of x, we need to understand what a function is. In mathematics, a function is a relation where every input (x-value) is uniquely paired with an output (y-value).
In this case, the equation is y = -17. Here, y is always equal to -17, regardless of the value of x. This means that for every value of x, the corresponding value of y is always -17.
Therefore, in this equation, y is not dependent on x, as it does not change with different values of x. As a result, we can conclude that the equation y = -17 does not define y as a function of x.
