## Algebra and Trigonometry 10th Edition

Vertex: $(-2, 4)$ Directrix: $x=-\dfrac{7}{4}$ Focus: $(\dfrac{-9}{4},4)$
We need to write the Standard form of a parabola: $(y-4)^2=4(\dfrac{-1}{4})(x+2)$ $h=-2$ and $k=4$ Vertex: $(-2, 4)$ Directrix: $x=h-p=-\dfrac{7}{4}$ Focus: $(h+p,k)=(\dfrac{-9}{4},4)$
