If f(x) = x2 + 2x + 3, what is the average rate of change of f(x) over the interval [-4, 6]?

a_sh-v [17]

Calculating the value of f(x) for the given interval.

For x = - 4, f(x) = f(- 4) = (- 4)^2 + 2 (- 4) + 3 = 11

For x = 6, f(x) = f(6) = (6)^2 + 2 (6) + 3 = 51

Now using formula for the calculation of average rate of change of f(x) over the given interval of [- 4, 6];

(f(b) – f(a)) / b – a = (f(6) – f(- 4)) / 6 – (- 4) = (51 -11) / 10 = 4

<span>So option “E” is correct.</span>

Answer:

$\frac{1}{2}$

Step-by-step explanation:

Thinking process:

Let the total set be the combination of all the sets as shown

It means that total items = 7 + 14 + 7 + 2

= 30

But the total number of the subsets = 5 + 7+ 2

= 14

Therefore the probability = $\frac{snap chat}{total }$

= $\frac{7}{14}$

= $\frac{1}{2}$
