For a relation to be a function, it can only have 1 of each number as an X value.
 If there are 2 or more identical X values it cannot be a function.
 The X value is the first value inside the parenthesis. (X,Y)


A has 2 3's as an X value so cannot be a function.
B has 2 2's as an X value so cannot be a function.
C  has no multiple X values so is a function.
D has 2 -2's as an X value so cannot be a function.

 The answer is C.

What is the sum of the geometric series in which a1 = −5, r = 3, and an = −405?
marysya [2.9K]
An = a1 * r^(n-1)

-405 = -5*3^(n-1)

3^(n-1) = 81

3^4 = 81  so n-1 = 3  and n =  4

Sn  = S4  =  -5 (1 - 3^4)   / ( 1 - 3)   =  400 / -2 = -200 Answer
