Determine turning points of a polynomial

WebThe degree of a polynomial function helps us to determine the number of x-intercepts and the number of turning points. A polynomial function of nth degree is the product of n factors, so it will have at most n roots or zeros, or x-intercepts. The graph of the polynomial function of degree n must have at most n – 1 turning points. This means ...

WebThe graph of a polynomial will touch and bounce off the x-axis at a zero with even multiplicity. The end behavior of a polynomial function depends on the leading term. The graph of a polynomial function changes direction at its turning points. A polynomial function of degree n has at most n – 1 turning points. WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2.
