An object was thrown from the top of a building. The height of the object above the ground can be found using the function y = -2.5x +75, where x is the time in seconds the object has been in the air. What is the domain of the function for this situation? a 0 ≤ x ≤ 30
b -2.5 ≤ y ≤ 75
c 0 ≤ x ≤ 72.5
d -187.5 ≤ y ≤ 2,250

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
