Find all real values of x such that f x 0

WebSolution. Always go back to the fact that the zeros of functions are the values of x when the function’s value is zero. We can see that when x = -1, y = 0 and when x = 1, y = 0 as well. Hence, the zeros of f (x) are -1 and 1. Example 2. The graph of f (x) is shown below. WebOkay, so we're giving a bunch of conditions and we're gonna try and use these to sketch a pretty accurate graph of our function F. Of X. And so the first thing I'm gonna do is try and figure out if these points at 02 and four are actually minimums are maximum values.

Notice that the graph of f crosses the x -axis at − 3, − 2, 0, 2 and 3. Using the fact f ( x) > 0 on the interval where the graph is above the x -axis, and f ( x) < 0 on the interval where the graph is below the x -axis we have: Find where it crosses 0. Use open intervals in between. Ex (3, ∞) WebThe Function which squares a number and adds on a 3, can be written as f (x) = x2+ 5.
