Domain and Range of Word

LNHS Algebra 1 Club decided to do a COOKIE fundraiser. It cost $10 to buy the supplies to make the cookies. The graph shows the relationship between cookies sold and earnings. What is the domain of the graphed function?

• -10 < y < 14 where f(x) is all integers

• 0 < x < 8 where x is all non-negative integers

• 0 < x < 10 where x > 0

• 0 < y < 8 where f(x) is all whole numbers

A student borrowed $480 from a friend. He agreed to make monthly payments of $96 with no interest until the loan balance was paid off. The function shown models this situation, where f(x) represents the remaining loan balance in dollars after the student has made x monthly payments. Which statements are true about the domain and range of the function for this situation? Select the correct answers.

• D: {0, 1, 2, 3, 4, 5}

• R: {0, 96, 192, 288, 384, 480}

• D: all real numbers

• R: {0, 1, 2, 3, 4, 5}

• : {0, 96, 192, 288, 384, 480}

• D: {0, 96, 192, 288, 384, 480}

• R: all real numbers
