To find the average value of the function \( f(x) = e^{x} \) from \( x = 0 \) to \( x = 2 \), we use the formula for the average value of a continuous function on the interval \([a, b]\): \[ \text{Average value} = \frac{1}{b-a} \int_a^b f(x) \, dx \] In this case, \( a = 0 \) and \( b = 2 \). Thus, we have: \[ \text{Average value} = \frac{1}{2-0} \int_0^2 e^x \, dx = \frac{1}{2} \int_0^2 e^x \, dx \] Next, we compute the integral \( \int e^x \, dx \): \[ \int e^x \, dx = e^x + C \] Now, we evaluate the definite integral from 0 to 2: \[ \int_0^2 e^x \, dx = [e^x]_0^2 = e^2 - e^0 = e^2 - 1 \] Substituting this back into the average value formula gives us: \[ \text{Average value} = \frac{1}{2} (e^2 - 1) \] Thus, the average value of the function \( f(x) = e^{x} \) from \( x = 0 \) to \( x = 2 \) is: \[ \text{Average value} = \frac{e^2 - 1}{2} \]
