Answer:
B is the answer as it's means intersection and none of the numbers intersect x and y
Reduce the common factors of the top and bottom of the fraction. You should be left with (-2d^2 ef^4)/3
I don't think this is possible.
The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3
And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0
Sorry but there is not an answer. :(
F ( x ) = 7 x + 2
y = 7 x + 2
- 7 x = - y + 2 /*(-1)
7 x = y - 2 / : 7
x = y/7 - 2/7 = ( y - 2 ) / 7
The inverse of the function is:
f^(-1) ( x ) = ( x - 2 ) /7
