Show that the curve y = 4 x 3 + 7 x − 5 y=4x3+7x-5 has no tangent line with slope 2 2. y = 4 x 3 + 7 x − 5 ⇒ m = y ' = y=4x3+7x-5⇒m=y′= Preview , but x 2 x2 0 0 for all x x, so m ≥ m≥ for all x x.

due to the symmetry of 
and the positive coefficients of the polynomial. If the function is evaluated at 
, where the minimum occurs, it is evident that the smallest value is 
. Therefore, the inexistence of any tangent line with slope 2 associated with that curve is true.
