Rational Zero Theorem

This video explains how to use the rational zero theorem to find all of the possible rational zeros of a function. The ratio of p over q is used where p is the factors of the constant term of the function and q is the factors of the leading coefficient. Sample problems are solved that find all of the possible rational roots and then also demonstrates how to find all real roots using polynomial long division and factoring and also to find any non-real roots as well.

Concavity and Inflection Points

มุมมอง 3413 ปีที่แล้ว

Concavity and inflection points of a function are defined and this video explains how to find the interval on which the function is concave up or concave down and where the inflection point is. A function is concave up (or upwards) where the rate of change is increasing. Similarly, the function is concave down (or downwards) where the rate of change is decreasing. Graphically, a graph that's co...

Average Rate of Change

มุมมอง 4713 ปีที่แล้ว

This video explains how to calculate the average rate of change for a non-linear equation. The average rate of change is calculated with the ratio of the change of y over the change of x but unlike a linear function that rate of change is different at different intervals. A secant line is a straight line joining two points on a function. The average rate of change is the slope of the secant lin...

Polynomial Long Division

มุมมอง 9103 ปีที่แล้ว

This video explains how to use polynomial long division to divide two polynomials. Long division of polynomials follows the same steps as long division of real numbers. If the polynomials involved were written in fraction form, the numerator is the dividend, and the denominator is the the divisor. To divide polynomials using long division, first divide the first term of the dividend by the firs...
