So f of x-- so 0 is less than or equal to f of x. Quadratic functions together can be called a family, and this particular function the parent, because this is the most basic quadratic function (i.e., not transformed in any way).We can use this function to begin generalizing domains and ranges of quadratic functions. The function has only negative values of y.Also, we see that we have , so the horizontal asymptote is equal to .Therefore, the range is all values less than -1. The domain is the set of all values which a function can take so, in this function, all the real value can be taken hence, the domain of this function is R Step 4 range the range is the set of all the values a function can give when we put the values of x where \(\displaystyle{x}\in{R}\) in this equation, the range of a function is all the . On the other hand, growing power functions will overtake logarithmic functions for large values of x. Domain and Range . Name:_____. 1. p is a non-negative integer . Rule that relates 2 quantities. Observe that when the function is positive, it is symmetric with respect to the equation $\mathbf{y = x}$.Meanwhile, when the function is negative (i.e., has a negative constant), it is symmetric with respect to the equation $\mathbf{y = -x}$..
