A) f(-1)= -4
B) f(-1)= 3
C) f(-1)= 1/4
D)f(-1) = 1/3

c  f(-1) = 1/4

Step-by-step explanation:

f(x) = x-1

      x^2 -9

Let x=-1

f(-1) = -1-1

         (-1)^2 -9

f(-1) = -2

         1 -9

     =-2/-8   = 1/4

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
