Using Desmos, what can you do to most efficiently find the correct answer to the question?

• Plot the ordered pairs and connect the dots

• Enter the table of data and generate the line of best fit, matching the equation of that line to the equation choices

• Substitute the x value in each row into each equation and evaluate the function to see if you get the corresponding y value shown in the table

• Input each answer choice as an equation, convert each to a table and select the function whose table matches the table in the problem

What does the heavy dot between the f(x) and the g(x) tell you to do with the expressions?

• multiply

• add

• factor

• Find the GCF

The explicit formula of an arithmetic sequence includes the first term of the sequence. (The first term is the a1)

• True

• False

Tags

CCSS.HSF.BF.A.2

The slope of the explicit formula of an arithmetic sequence is the common difference of the sequence.

• True

• False

Tags

CCSS.HSF.BF.A.2

Which method could be the most efficient to find the correct answer?

• Draw blank spaces for terms 1-9 and work backwards using the common difference to fill in the blanks.

• Establish the common difference as +17 or -17, narrow down your answer choices, type those remaining functions into Desmos (using x instead of a_n-1) and convert to a table to find the matching term positions and values.

• Start sequences with both -238 and -221, applying the common difference until you get to the 10th, 11th and 12th terms.
