WebOct 6, 2024 · Note that this inequality has the form \(f(x) \leq 0\), where \(f(x)=0.25 x^{2}-1.24 x-3.84\). Our strategy will be to draw the graph of f, then determine where the graph of f lies below or on the x-axis. We proceed as follows: First, load the function f(x) = 0.25x 2 − 1.24x − 3.84 into the Y1 in the Y= menu of your calculator. WebIn other words, we are looking for the x-intercept, since y=0 for all x-intercepts. So we substitute 0 in for f(x) and we get: Now we solve for x Add 12 to both sides Divide both sides by 3. This will isolate x. So if we let x=4 we should get f(x)=0, in other words, f(4)=0. So lets verify this: Check: Plug in x=4 works This verifies our answer

WebSep 18, 2024 · 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 slope is just 5 everywhere, so f'(x) = 5. Then f''(x) is the slope of a horizontal line--which is 0. So …
