Determine whether each equation is correct

Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

On a piece of paper, graph . then determine which answer choice matches the graph you drew

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
