Answer to determine the domain and range of the quadratic function. Look at the graph below to understand what i mean. 2 answers dean r. Therefore the domain of the quadratic function in the form y ax 2 bx c is all real values.

The general form a quadratic function is y ax 2 bx c. When using interval notation domain and range are written as intervals of values. Finding inverses of rational functions as with finding inverses of quadratic functions it is sometimes desirable to find the inverse of a rational function particularly of rational functions that are the ratio of linear functions such as in. It s always wonderful to see.

F x has domain latex 2 le x 1 text or x ge 3 latex or in interval notation latex left 2 1 right cup left 3 infty right latex. However it is much better to write it in set notation or interval notation. D indicates that you are talking about the domain and read as negative infinity to positive infinity is another way of saying that the domain is all real numbers the range of f x x 2 in interval notation is.

Jun 28 2018 the domain is all real numbers and the range is all the reals at or above the vertex y coordinate if the coefficient on the squared term is positive or all the reals at or below the vertex if said coefficient is negative. Enter your answers using interval notation f x 5 x 2 2 10. Given a situation that can be modeled by a quadratic function or the graph of a quadratic function the student will determine the domain and range of the function.

Here s the summary of the domain and range of the given function written in two ways because the function involved is a line i can predict that the range is all y values. Hence the range of f is therefore given by the interval. Algebra expressions equations and functions domain and range of a function.
