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.
How to use graph to determine where f(x) > 0 and f(x) < 0

WebApr 18, 2024 · the function f (x) = (x + 2) (x + 6) LEts find the x intercept of the given function 0 = (x+2) (x+6) x+2=0 so x=-2 x+6 = , so x=-6 x intercepts are -6 and -2 Lets draw a number line and use x intercepts and make 3 intervals - infinity to -6 , -6 to -2 and -2 to infinity LEts pick a number from each interval and check with f (x) x<-6, pick -7 WebOct 14, 2016 · 2 Answers. 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. The same notion may also be used to show how a function affects particular values. Example. f (4) = 4 2 + 5 =21, f (-10) = (-10) 2 … soins henriville
