Note that (a+b)^2 = a^2 + 2ab + b^2.

Therefore, 
                                                                              b^x         (b^x )^2
<span>(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
                                                                                 2               4

LCD is 4.  Thus, we have
                                             
            4 [ (2a^(2x) ] + 8</span>a^x*b^x + b^(2x)
<span>                                  </span>

What is the average rate of change of the function f(x) = 5x ^ 2 + 20x between x = 0 and x = 0.5
Vitek1552 [10]

9514 1404 393

Answer:

  22.5

Step-by-step explanation:

The average rate of change on the interval [a, b] is the ratio ...

  (f(b) -f(x))/(b -a)

For your function and interval, it is ...

  (f(0.5) -f(0))/(0.5 -0)

Since f(0) = 0, this reduces to ...

  average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)

  average rate of change = 22.5
