Answer:
the full circle one
Step-by-step explanation:
use the vertical line test. Hold up a pen on any given spot in the graph (the pen has to be vertical) and if it goes through the line in 2 or more different places its not a function
C. y = 8x
When x = 1
y = 8(1) = 8
when x = 2
y = 8(2) = 16
x increased by 1
y increased by 8
r=-6
You have to use distributive property and multiply parentheses
