<span>The doctor cannot perform more than seven follow-ups per day.
</span>y ≤ 7

<span>The hospital has eight hours available for appointments.
</span>x + 0.5 y ≤ 8

And the hospital earns a total amount of z
120x + 70x = z

Let f(x)=x^2+2x+3 . What is the average rate of change for the quadratic function from x=−2 to x = 5?
miskamm [114]
To find the average rate of change of  given function f(x) on a given interval (a,b):

Find f(b)-f(a), b-a, and then divide your result for f(b)-f(a) by your result for b-a:


f(b) - f(a)
------------
    b-a

Here your function is f(x) = x^2 - 2x + 3.  Substituting b=5 and a=-2,
f(5) = 5^2 -2(5)+3 =?                          and f(-2) = (-2)^2 - 2(-2) + 3 = ?


Calculate           f(5) - [ f(-2) ]
                         ------------------ using your results, above.
                              5 - [-2]

Your answer to this, if done correctly, is the "average rate of change of the function f(x) = x^2+2x+3 on the interval [-2,5]."

Write an explicit rule for the geometric sequence 4, 8, 16, 32, ..
Paul [167]
First term:  a(1) = 4; common ratio:  r = 2

Then:

a(n) = 4(2)^(n-1)

Check:  Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32  (correct)
