Answer:
A pile of pennies
Step-by-step explanation:
Both exponential i.e 5 ^x
A is true, surprisingly.
B cannot be true, it alternates.(rule of indices negatives by positive exponent = positive, negative by negative , but -5 x -5 x -5 = + 5)
I'm only imaginging, but C must be right, since it increases exponentially, as opposed to D which only increases quadratically.
The solution is:
y = 3
and
x = 5
first one it is the absolute value of -3 and the other one is -3 itself absolute value of -3 mean 3
