Factor Theorem - ANS-A polynomial f(x) has a factor (x - a) if and only if f(a) = 0 It has a factor (bx-a) if f(a/b) = 0 Sketching polynomials - ANS-Shape: Reflect in x-axis if there is a negative x Roots: - Crosses x-axis at any root e.g. (x+5) would mean crosses at negative 5 -However, if negative x is in the bracket e.g. (5-x) would mean crosses at positive 5 -Also a repeated root means the curve just touches at that point Sketching graphical inequality - ANS-Shade where the inequality ...
