The graph below plots a function f(x): graph of line segment going through ordered pairs 0, 100 and 3, 220 if x represents time, the average rate of change of the function f(x) in the first three seconds is

Average rate of change of a line is its slope.

To find slope we can use the formula:

Where,

For our problem,

Now, let's find slope.

So, the average rate of change of the function f(x) int he first three seconds is 40.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
