Find Domain And Range Using Interval Notation

Interval notation is a method used to write the domain and range of a function.

Find domain and range using interval notation. Infinity range is 4 infinity g t 3 sin t. Use notations to specify domain and range. On the parabola the first x value is 8 and the last is 12 so we have to write this in interval notation which is 8 12.

Open parentheses closed parentheses infinity imagine an 8 sideways negative infinity an 8 sideways with a negative sign in front of it and union a symbol similar to an elongated u. Using a parenthesis means the boundary is not included in the set.

Remember that when writing or reading interval notation using a square bracket means the boundary is included in the set. So let s do domain first. The one to one function is defined by f x 7x 5 8 5x find f 1 the inverse of f.

For the domain and the range we approximate the smallest and largest values since they do not fall exactly on the grid lines. In the previous examples. Updated video in hd here.

In interval notation the domain is 1973 2008 and the range is about 180 2010. Find domain and range using interval notation. Then give the domain and range of f 1 using interval notation.
