Can a function be a horizontal line
WebThe Horizontal Line Test allows you to check, from the graph of a function, whether that function's inverse will also be a function. If there is any place on the graph of the original function where a horizontal line would cross two more more times, then the inverse of that function will not itself be a function. If all horizontal lines cross ... WebDec 28, 2024 · The four points we obtained where the limacon has a horizontal tangent line are given in Figure 9.47 with black--filled dots. To find the vertical lines of tangency, we set the denominator of \(\frac{dy}{dx}=0\).

WebJun 17, 2015 · Explanation: Example: f (x) = 3 on the interval [2,7] has maximum value 3 and minimum value 3. All the is required to be the absolute maximum value is that there is no greater value. All that is requires to be the minimum value is that there is no lesser value.
