Is the inverse of a quadratic a function?

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

Heather is riding a quadratic function that represents a parabola that touches but does not cross the x-axis at x=-6
