A098- Writing a Function Rule

Write the function rule for each table of values. A098_1

$y = x + 1$

$y = 2x + 1$

$y = 3x - 1$

$y = 4x- 2$

Question 1 of 8

Write the function rule for each table of values. A098_2

$y= x + 1$

$y= x - 1$

$y = x - 3$

$y= x -2$

Question 2 of 8

Write the function rule for each table of values. A098_3

$y= 2x + 7$

$y= 5x - 2$

$y = 4x - 3$

$y= 5x$

Question 3 of 8

Write the function rule for each table of values. A098_4

$y= 2x - 7$

$y = -3x + 2$

$y = 4x - 15$

$y = -2x + 16$

Question 4 of 8

A resort charges $20 a day to rent a boat. However the customers must pay a $99 initiation fee to start renting. Write a function for the total cost to rent a boat for “d” days.

$f(d) = d + 99$

$f(d) = 99d + 20$

$f(d) = 20d + 99$

$f(d) = 20d - 99$

Question 5 of 8

Bob wants to buy pineapples (represented by x) which are 25 cents each and bananas (represented by y) which are 50 cents each. Write a function that represents the total cost “c” for buying bananas and pineapples.

$c = .25x + .5y$

$c = .25x - .5y$

$c = (.25x)(.5y)$

$c= \frac{.25x}{.5y}$

A company needed copy paper for their office staff. The cost was $60 per box, $b,$ of copy paper. They also had to pay $40 for a shipping fee. Write the function for the cost, $c,$ of the copy paper per box.
