  3. How to find the range of a function (video) | Khan Academy

    www.khanacademy.org/.../v/range-of-a-function

    The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of possible outputs.

    The graph of y=log base 2 of x looks like a curve that increases at an ever-decreasing rate as x gets larger. It becomes very negative as x approaches 0 from the right. The graph of y=-log base 2 of x is the same as the first graph, but flipped over the x-axis. The graph of y=-log base 2 of (x+2) is the same as the first graph, but shifted to the left by 2.

  7. Find the domain, range, and zeros of the function? HELP

    support.khanacademy.org/hc/en-us/community/posts/115000969147-Find-the-domain...

    When you are asked for the domain, you are to identify where a function exists with respect to the x-axis. As the x-axis is the horizontal axis (left to right), you would want to note the arrows on either end of the parabola.
