For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0....

Now we should figure out when the argument of the square root is positive. Finding the roots of this equation tells us that x = 0 and x = 12 When is x(x - 12) > 0? You can figure this out a few ways. If you have a graphing calculator, plot this function. If y...
Domain & Range of a Function | Definition, Equation & Examples from Chapter 7/ Lesson 3 231K What are the domain and range of a function? What are the domain and range of the graph of a function? In this lesson, learn the definition of domain and range as it applies to...
Sketch the domain of integration of and evaluate the following double integral:{eq}\qquad \displaystyle \int_{x\,=\,0}^{3/2}\int_{y\,=\,2x}^3 (y^2+16)^{1/2}\ dy\ dx. \, {/eq}Double Integral:To calculate the double integral of a ...
domain of a function, start with the easy stuff: first look for any values that cause you to divide by zero. Remember also that we cannot take the square root of a negative number, so keep an eye out for situations where the radicand (the "stuff" inside the square root sign) could ...
