I am not sure about any of my answers and I don’t know how to find the range for question b or the slope for question c.

a) is correct

b) y = -a(x - 2.5)² + h

(5.5,0)

0 = -a(5.5-2.5)² + h

h = 9a

a = h/9

48 = -a(0-2.5)² + h

h = 48 + 6.25a

h = 48 + 6.25(h/9)

h = 157.0909090681

Range: [0,157]

c) (80-144)/(4.5-3)

= -42⅔ or -42.67

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

the answer is su.k.my? ? co.kc
