Geometric Interpretation of Rolle's Theorem In the given graph, the curve y = f (x) is continuous between x = a and x = b and at every point, within the interval, it is possible to draw a tangent and ordinates corresponding to the abscissa and are equal then there exists at least one tangent to the curve which is parallel to the x-axis.Rolle’s Theorem is a special case of the mean-value theorem of differential calculus.. It expresses that if a continuous curve passes through the same y-value, through the x-axis, twice, and has a unique tangent line at every point of the interval, somewhere between the endpoints, it has a tangent parallel x-axis. Rolle's Theorem. Rolle's theorem states that if f is a function that satisfies: 1. f is continuous on the closed interval a &comma; b, 2. f is differentiable on the open interval (a &comma; b), and. 3. f &ApplyFunction; a &equals; f &ApplyFunction; b. then there exists a point c in the open interval (a &comma; b) such that f'(c) = 0. Geometric Interpretation of Rolle's Theorem In the given graph, the curve y = f (x) is continuous between x = a and x = b and at every point, within the interval, it is possible to draw a tangent and ordinates corresponding to the abscissa and are equal then there exists at least one tangent to the curve which is parallel to the x-axis.Aug 05, 2011 · Step 1: Find out if the function is continuous. You can only use Rolle’s theorem for continuous functions. This function f (x) = x 2 – 5x + 4 is a polynomial function. Polynomials are continuous for all values of x.
