If f(x) is a function and f(1) = 5, then which of the following could not be true? a.)f(1) = 1 b.)f(2) = 1 c.)f(5) = 5

The choice a could not be true because the value of f(1) is already equal to 5. Therefore, the value of f(1) cannot be 1. This is one of the properties of a function that for every value of x, there should be only one corresponding value of y.

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

i would pic false cause it goes down towards negative
