horizontal tangent
[horizontal tangent|horizontal tangent] The function f(x) = x?
Mechanism
horizontal tangent The function f(x) = x? - 7x? + 8x +1 has a horizontal tangent line where its derivative equals zero. This occurs when the derivative's values determine the x-values for which the tangent is horizontal.
Causes
horizontal tangent The function f(x) = x? - 7x? + 8x +1 has a horizontal tangent line where its derivative equals zero. This occurs when the derivative's values determine the x-values for which the tangent is horizontal.
Effects
horizontal tangent [horizontal tangent] occurs when the derivative of a function equals zero, indicating a horizontal tangent line at that point.
