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.
1 answer:
Answer:
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
