Answer: Direction opens downward

Step-by-step explanation:

X-Intercept: (1/14,0),(-1/4,0)

Y-Intercept: (0,1)

Find the vertex using x= -b/2a

Plug it into the vertex form = y=a(x-h)^2 +k

H,K will identify the direction.

Answer:

11.4

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

1. $d=\sqrt{(-4-5)^2+(-3-4)^2}$

2. $d=\sqrt{(-9)^2+(-7)^2}$

3. $d=\sqrt{81+49}$

4. $d=\sqrt{130}$

5. $d=11.4017$

6. $d=11.4$
