WebMay 2, 2024 · Example $\PageIndex{2}$ Identify the graphs of the polynomials in (a), (b) and (c) with the functions (i), (ii), and (iii). $f(x)=-x^3+9x^2-27x+29$ $f(x)=-x^2+6x-7$ … WebExample: 2x+1. 2x+1 is a linear polynomial: The graph of y = 2x+1 is a straight line. It is linear so there is one root. Use Algebra to solve: A "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 (You can also see this on the graph)
