Answer:
C
Step-by-step explanation:
A function is a rule that assigns exactly one output to each input. This means the input values of the function cannot repeat with different output values.
Tables A, B, and D have repeating input values in the x row (the second row). This means they are NOT functions.
C is the solution.

Sorry if that is wrong
X^2 = 16
x = 4
x = -4

Answer:
CS = 4
Step-by-step explanation:
From the figure below;
Triangle ABC is similar to triangle RSC
Therefore, the ratio of the corresponding sides in the two triangles is equal;
That is;

In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS
But; 
AC=CR + RA
= 5
Assuming CS is y, then


Therefore, CS is 4
