Answer:
x=0
Step-by-step explanation:
Answer:
7. inverse relationship; equation: y = 16/x
8. no relationship; no equation
Step-by-step explanation:
The attachment shows the support for the conclusions. The relationship can be chosen from those offered by looking at differences, ratios, or products of y-values for sequential x-values.
- linear: constant differences
- exponential: constant ratios
- inverse: constant products

<h3>7.</h3>
In the first problem, we note that the relationship between y-values varies inversely as the relationship between x-values: when x goes up by a factor of (n+1)/n, the value of y goes down by its inverse factor: n/(n+1). That same relationship is observed by noting that the product of x and y is a constant, 16.
relationship: inverse
y = 16/x

<h3>8.</h3>
As we looked at the table, we thought this might be an exponential function. Each y-value seemed to be twice the one before—until we got to x=5. As x went from 4 to 5, the y-value increased by a factor of 16, not 2. This means there is no simple relationship between x and y, and no simple equation that will describe the sequence of y-values.
Answer:
(d) ∞
Step-by-step explanation:
The expression can be simplified to one that is not indeterminate:
A polynomial with a positive leading coefficient will tend to infinity as x goes to infinity.
