F(x)=-x^2 - 4x
find f (-1)

Describe the relationship between the angles of similar triangles and the sides of similar triangles

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585

Pleting the square f the given find the x-intercepts of the parabola with vertex (-5,13) and y-intercept (0, 12). write your answer in this form: (14,.99). if necessary, round to the nearest hundredth. *- h enter the correct answer, de verter, and ametry 00000 done doo
