The ordered pairs (1, 81), (2, 100), (3, 121), (4, 144), and (5, 169) represent a function. What is a rule that represents this function? (1 point)y = x8 y = 8x y = (x + 8)2 y = 8x 2. Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.59. (1 point)c(p) = 59p c(p) = c(p) = p + 0.59 c(p) = 0.59p 3. A snail travels at a rate of 2.35 feet per minute. Write a rule to describe the function. How far will the snail travel in 5 minutes? (1 point)d(t) = 5t; 11.75 ft. d(t) = t + 2.35; 7.35 ft. d(t) = ; 2.13 ft. d(t) = 2.35t; 11.75 ft.

    For #1, notice that all the y values are square numbers.

    Look at that first point (1,81), what number is 81 the square of?

    Yes, 2 and 3 are the fourth option. Right, so to get from x=1 to y=81, you need to add 8 to 1 to make 9 and then square it. y=(x+8)^2 Make sense? Check that with the other points too, to make sure it works for them as well.
