    • 2. a. (x + 4)(x + 3.5) = 0 b. 2(x – 2)(x – 6) = 0 c. (x + 3)(x – 7)(x + 8) = 0 d. x(x – 9)(x + 3) = 0 2. Graph each equation and then rewrite it in factored form. a. y = x2 – 4x + 3 b. y = x2 + 5x – 24 c. y = x2 + 12x + 27 computation d. y = x2 – 7x – 30 3. Name the x-intercepts of the parabola described by each quadratic equation. Then check your answers with a graph. a. y = (x – 7)(x + 2) b. y = 2(x + 1)(x + 8) c. y = 3(x – 11)(x + 7) d. y = (0.4x + 2)(x – 9) 4. Write an equation of a quadratic function that corresponds to each pair of x-intercepts. Assume there is no vertical stretch or shrink. a. 2.5 and –1 b. –4 and –4 c. –2 and 2 d. r 1 a 5. Consider the equation y = (x + 1)(x – 3). a. How many x-intercepts does the graph have? b. Find the vertex of this parabola. c. Write the equation in vertex form. Describe the transformations of the parent function, y = x2 . Reason and Apply Key Press.
