Convert the following quadratic function from vertex form to standard form.

1. f (x) = - 3 (x-4) ^2+7

The vertex of a parabola is (-1.5, - 12.5), and its y-intercept is (0, - 8) The x-intercepts of the parabola are: (-2, 0), (-4, 0), (2, 0), (4, 0) and (-1, 0), (2, 0), (1, 0), (-2, 0)

On a multiple choice test with 13 questions, each question has four possible answers, one of which is correct. for students who guess at all answers, find the standard deviation for the number of correct answers.

Simplify 7x + (x - 4) (x + 5) - 5x. x2 + x - 20 x2 + 3x - 20 x2 - 3x - 20 x2 - x - 20

Which equation can be used to determine the distance between the origin and (-2, - 4) ? d = StartRoot ((0 minus 2) + (0 minus 4)) squared EndRoot d = StartRoot (0 minus (negative 2)) squared + (0 minus (negative 4)) squared EndRoot d =
