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

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
