A)
q and r are your x intersects
so q=-2 and r=4
-> f(x)=p(x-(-2))(x-4)
=p(x+2)(x-4)

b) your axis of symmetry is at x=1

c) to calculate p use the point (0,-4) and insert it:

f(0)=y=-4=p*(0+2)*(0-4)
-4=p*2*-4
-4=p*-8
p=1/2

What is the average rate of change of f over the interval -7 < or equal to x Give an exact number

Annette [7]

Answer:

$\frac{4}{3}$

Step-by-step explanation:

The average rate of change can be found by using the following formula

$\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}$

Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.

By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.

Now that we know this, we can simply plug these values into the formula!

$\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}$

Good luck!
