6. Elana is making some yarn art by attaching pieces of yarn to a grid in the shapes of different functions, allowing them

to cross and make an original design. One strip of yarn is in the shape of a parabola that opens downward, has a vertex

at (–5, 4) on the grid, and passes through the point (-3, 0). What is the equation of the parabola (in vertex form) Elana

makes with the yarn? Show your work.
