What is the Inverse of function ? f(x) = x + 7
-
A. 1-1(x) = (t – 7), for x > 7
B. 1-1(x) = (x + 7), for * > -7
C. 1-1(x) = x2 + 7, for I > -7
D. 1-1) = r2 - 7, for I > 7
=

step-by-step explanation:

y=mx+b

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1
