Polynomials, Part 1: Zeroes and their graphs
Where a graph meets the -axis, the polynomial is zero.
In this lesson you will
- Identify polynomials and their degree
- Find the zero of a linear polynomial and test whether a number is a zero
- Read the number of zeroes and their values from the graph of y = p(x)
- Describe the shapes of graphs of linear, quadratic and cubic polynomials
- Interpret zeroes in real situations and reject meaningless ones
