What is the average rate of change for this quadratic function for the interval from x= -5 to x= -3?
A. 16
ОО
B. -8
C. 8
D. -16

hi the answer should be C or 8

Step-by-step explanation:

Hope this helps!

8

Step-by-step explanation:

The average rate of change is given by

f(x2) -f(x1)

x2-x1

x2 = -3  and x1 = -5

Looking at the graph

f(x2) = f(-3) = 1

f(x1)= f(-5) =-15

Substituting these values into the equation

1 - (-15)

-3 - (-5)

1+15

-3 +5

16

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
