Solving Quadratic Equations: Quadratic Formula — Cumulative exam Answers

The equation for the line of best fit is f(x) ≈ 1.8x − 5.4 for the set of values in the table.

Which is the graph of the sequence defined by the function f(x) = 100(0.5)x - 1?

The steps in writing f(x)=18x+3x2 in vertex form are shown, but a value is missing in the last step.Write the function in standard form. Factor a out of the first two terms. f(x)=3(x2+6x)Form a perfect square trinomial. f(x)=3(x2+6x+9)−3(9) Write the trinomial as a binomial squared. f(x)=3(x+___)2−27
