Writing Quadratic Equations Regression

Write the equation of the parabola shown.

• y = 2x² + 4x - 5

• y = 2x² - 4x + 5

• y = 2x² + 4x + 5

• y = 2x² - 4x - 5

Write an equation in Factored Form, whose solutions are 7 and 3.

• y = (x - 7)(x - 3)

• y = (x + 7)(x + 3)

• y = (x + 7)(x - 3)

• y = (x - 7)(x + 3)

What are the x-intercepts for the graph?

Write the equation for the graph in factored form.

Calculate the quadratic regression function for this table of values to the nearest tenth.

• f(x) =
   2x² - 9x + 10

• f(x)=
   3x² + 9x - 10

• f(x) =
   3.1x² - 9.2x - 10.3

• f(x) =
  2.1x² - 8.6x + 10.1
