<span><u><em>The correct answer is:</em></u>
B.
<u><em>Explanation:</em></u>
In order to find the appropriate equation for this example, we need to <u>find one that works for the first point (1, 56). </u>
This means when we put 1 in for n in the equation, we need to get 56 as an answer.
If you place 1 in for n in each of the equations, only B gives you 56.
f(n) = 56(0.5)</span>ⁿ⁻¹<span>,
f(n) = 56(0.5)</span>⁰<span>,
f(n) = 56(1),
f(n) = 56. </span>
Answer:
100
Step-by-step explanation:
For y to not be a function of x, there needs to be an x-value that is paired with more than one y-value.
In terms of the sets, you need to find a set where the same x-value is used more than once in two (or more) different (x,y) pairs.
This occurs in the third set, where x=6 is used twice.
Subtracting 7 and dividing by -3 on both sides shows us that y = -9
