First of all, I'd suggest that you use a new, clean, blank line for every bit of new information.

-1/4 divided by 3/2 = -4/1 times 3/2     Do NOT insert another " = " sign here, but move on to a new line.  

"<span>-1/4 divided by 3/2 = -4/1 times 3/2 =-12/2 = -6"

You are dividing -1/4 by 3/2.  To do this, invert 3/2 and then multiply:

-1       2
---- * ---- = -1/6
 4        3

Notice how I have only ONE " = " sign here.</span>

Calculate the average rate of change of the quadratic function y = -x2 + 4x +2
algol13

Answer:

2

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [ 0, 2 ], thus

f(b) = f(2) = -(2)² + 4)(2) + 2 = - 4 + 8 + 2 = 6

f(a) = f(0) = 2

average rate of change = \frac{6-2}{2-0} = \frac{4}{2} = 2
