This graph represents Option D =
As the given figure is a parabola, it will have quadratic equation because the general equation of parabola corresponds to which has highest power of the variable equals to 2, thus its a quadratic equation.
The maximum value of a quadratic equation is at points
By looking at the graph we can observe the point at which the graph has achieved maxima is (-2,4).
∴ ( ,
The coefficient of should be negative the graph opens downwards.
∴ Option B and C are eliminated.
On putting x = -2 only option D yields 4.
Thus this graph represents Option D =

First you have to estimate.
$3.98 —>$4.00
$4.19 —>$4.00
$0.79 —>$1.00
Then we need to add.
4+4+1=9
So the answer is C, $9
F'(c)=[ f(b)-f(a) ] / b-a in interval [a,b]
find f(2) or f(a) and find f(8) or f(b)
plug it into f'(c) that is above
once you find that find f'(x) and set it equal to f'(c) that you found in the previous step solve for x, or replace with c and that is your answer
