80 Find The Domain Of Each Function Using Interval Notation Update

All polynomials have a domain of all real numbers.

Find the domain of each function using interval notation. Check out the graph to see which values work for x. Means for each eq displaystyle x eq point in the domain eq displaystyle f x eq is valid. To find the domain of this type of function just set the terms inside the radical sign to 0 and solve to find the values that would work for x.

So the domain of the first one will come from solving. A function using the natural log ln. Then the domain of r t is the intersection of the domains of the components.

This will be a list of x and y. Stick with those and you will have a polynomial. On square roots you have to make sure the inside is positive or zero.

Click the blue arrow to submit and see the result. Other strategies for finding domain of a function the alternative of finding the domain of a function by looking at potential divisions by zero or negative square roots which is the analytical way is by looking at the graph. For number 10 interval notation.

Y 3x 1 y x 2 3x 2 and y x 3. In interval notation we write. The domain of a function is set such that each point on the domain has a point in the codomain.
