Given f(x) = 17-xwhat is the average rate of change in f(x) over the interval [1, 5]?

The average rate of change in f(x) over the interval [1, 5] is -1

Hi! Let me help you to understand this problem. Here we have the following function:

We need to compute the Average Rate of Change (ARC) in over the interval . So what is the average rate of change of a function? In general, for a nonlinear graph whose slope changes at each point, the average rate of change between any two points is defined as the slope of that line through that two points. Here we have a linear function, so the average rate of change will be the slope of the line:

So:

This can also be calculated as:

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
