The derivative is the slope of the tengant line to a function at a given point

and x = -3

Quand "Find the slope and an equation of the tangent at the point (x;y)" : - Calculer f'(x), puis calculer pour la valeur x - Nous avons mtn "m" et on résout l'equation

Note that f is a rational function and is not defined at points where the denominator equals 0. We have:.. for x =3 the function is undefined. The function is not continuous at x = 3 and x = −3.

The function is a polynomial defined on x ∈ R. Polynomial functions are continuous at every point in their domain. Hence, f has no points of discontinuity.
