What is the answer ?
1 answer:
Hi there! The answer is A.
In the graph we can see is a parabola (so B. cannot be the answer) with a vertex at the point (0, 0), which means the parabola is not translated upwards or downwards. Therefore, only A. can be correct, since all the other formulas include a translation downwards (which can be deduced from the -2 in the formula).

Example,
Example,
Let
x---------> the total number of coins
we know that
512 cents-------> is equal to $5.12
1 penny is equal to $0.01
1 nickel is equal to 5 penny--------> $0.05
1 dime is equal to 2 nickel--------> $0.10
the total number of coins are 96
Divide 96 by 3 to obtain the number of coins of each type
therefore
<u>the answer is</u>
the number of penny coins are
the number of nickel coins are
the number of dimes coins are
