Polynomial Functions y = anxn + an-1xn-1 + … + a1x + a0 Example: y = 6x4 – 5x2 + 2x - 5 Is a combination (adding/subtracting) of power functions (we look a bit more at this idea in 8.6- 8.7) Graph is studied in detail in Calculus Too complicated for us to look at much right now We will look at one special case of polynomials
y = ax2 + bx + c This function describes lots of things Flight of a ball Revenue (R = price*x, where price depends on x) Graph is always a parabola Could do this by simplifying to a(x-h)2 + k to see how it is shifted and stretched (and use techniques we’ll learn in 8.6-8.7). We will look at another way to analyze the
