How To Write Domain And Range Of A Quadratic Function

When quadratic equations are in standard form they generally look like this.
How to write domain and range of a quadratic function. Fx ax2 bx c. The structure of a function determines its domain and range. 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. How to find domain and range of a quadratic function.
To find the range you need to know whether the graph opens up or down. The domain of a quadratic function in standard form is always all real numbers meaning you can substitute any real number for x the range of a function is the set of all real values of y that you can get by plugging real numbers into x. When we look at the graph it is clear that x domain can take any real value and y range can take all real values greater than or equal to 0 25.
