The parabola opens down, since the 'a' value of the equation is a negative value.
The x intercept would be -2
and the y intercept would be 21
Part A...Y=9, Part B, m=54 degrees
Answer: 3/8,1/4,1/8
Step-by-step explanation:
an=a1+(n-1)d
using a bit of math the d= common difference and that's equal to -0.125 or -1/8.
So plug in the values
and the terms we need to get 3/8,1/4,1/8 as the next three terms.
