Answer:
Lower limit of the sum: 0
Upper limit of the sum: 17
Explicit formula: ∑(3+7i)
Step-by-step explanation:
Noting that each row has 7 more beads than the previous one and that the series also begins with 3, the formula is:
∑(3+7i)
The lower limit is 0, since 3+ (7 * 0) = 3
When i = 0 you get the value of beads from the first row, when i = 1 you get the value of beads from the second row and so on. Given this, the upper limit is 17.
A. Both and
have the <em>same</em> domain of
.
<h3>How to analyze similarities in two functions</h3>
In this question we must analyze the domain, range, x-intercepts and <em>increase</em> intervals:
<h3>Domain</h3>
Both functions are <em>continuous</em>.
<h3>Range</h3>
According to the graph,
increase over the interval of
.
According to the graph,
increase over the interval of
After a quick analysis, we conclude that option A offer the best approximation to characteristics of both functions.
