Monday, Jan 11 - Domain & Range Drill

Multiple Choice

The total cost in dollars, c, to purchase video games online can be found using the function c = 16.95x + 4.75, where x is the number of video games purchased.  If at least 4 games but no more than 7 games are purchased online, what is the range of the function for this situation?

• {4, 5, 6, 7}
• 4 ≤ x ≤ 7
• 72.55 ≤ c ≤ 123.50
• {72.55, 89.50, 106.45, 123.40}

Multiple Choice

What is the Domain?

• {-3, -1, 1, 3, 5, 7, 9}

• {-3, -2, -1, 0, 1, 2, 3}

• -3 ≤ x ≤ 3

• -3 ≤ x ≤ 9

Multiple Choice

What is the range of the function?

Hint: Graph counts by 2's.
