For what values of x is f x 0
WebMar 8, 2024 · The solution set of the equation ‘f (x)= 0 f ( x) = 0 ’ is shown in purple. It is the set of all values of x x for which f (x) f ( x) equals zero. That is, it is the set of x x -intercepts of the graph. The graph of a function f f is shown below. The solution set of the inequality ‘f (x) <0 f ( x) < 0 ’ is shown in purple. WebOct 14, 2016 · 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, ∞)

WebRemember that the value of f'(x) anywhere is just the slope of the tangent line to f(x). On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the …

WebJun 29, 2024 · The notation f(x) means that you take the function f, apply it to the input variable x, and receive some output. f(f(x)), then, means that you take the output of f(x) and apply the function f to it. Note that solving f(0) is very different to solving f(x) = 0. If the former case, you're setting the input to zero, and finding what the output is.
