Find the average rate of change for the function over the given interval.

jekas [21]

Answer:

The average rate of change for the function over the given integral

$A(x) = \frac{e^{-2} -1}{2}$

Step-by-step explanation:

Explanation

Average rate of a function:-

We can define the average rate of change of a function from a to b

$A(x) = \frac{f(b)-f(a)}{b-a}$

Given function f(x) = eˣ

Given interval x = a = -2 and y = b = 0

f(a) = f(-2) = e⁻²

f(b) = f(0) = e⁰

$A(x) = \frac{e^{-2} -1}{0-(-2)}$

Answer:

6.2 = Altitude

Step-by-step explanation:

Hypotenuse = 8

Base = 5

Altitude = x

Hypotenuse² = Base² + Altitude²

8² = 5² + Altitude²

64 = 25 + Altitude²

64 - 25 = Altitude²

39 = Altitude²

√39 = Altitude

6.2 = Altitude
