Question

The table shows values that represent a quadratic function

X Y
1 -2
2 -5
3. -10
4. -17
5. -26
6. -37

What is the average rate of change for this quadratic function for the interval from x =3 to x=5

Answer 1

Answer:

- 8

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 ] = [ 3, 5 ]

From the table

f(b) = f(5) = - 26

f(a) = f(3) = - 10

Hence

average rate of change = $\frac{-26-(-10)}{5-3}$ = $\frac{-16}{2}$ = - 8

Answer 2

Answer:

If your table has (4,32), (5,50), (6, 72) then the answer is 16
