Consider the equation f(x) = x^2-2x-15 PART A Decide if each point lies on the equation or not. True False PART B Pick the equation(s) that are equivalent to the original: a(x)=(x+3)(x-5) b(x)=x^2-(2/3)x-5 c(x)=-x^2+2x+15 d(x)=(x-1)^2-16 PART C Mark the 2 points where the equation's graph crosses the x-axis. PART D What is the minimum or maximum of the equation? Explain how you found it, and provide your reasoning on deciding between choosing minimum or maximum.
