Final answer:

To find the Taylor series for f(x) = e^2x at x = 1, we use the Taylor series formula. We find the derivatives of f(x) = e^2x and substitute the values into the formula to get the Taylor series.

Step-by-step explanation:

To find the Taylor series for f(x) = e^2x at x = 1, we will use the formula for the Taylor series expansion:

Taylor series: f(x) = f(a) + f'(a)(x-a) + f''(a)(x-a)^2/2! + f'''(a)(x-a)^3/3! + ...

First, find the derivatives of f(x) = e^2x:

f'(x) = 2e^2x

f''(x) = 4e^2x

f'''(x) = 8e^2x

Now substitute the values into the Taylor series formula:

Taylor series: f(x) = f(1) + f'(1)(x-1) + f''(1)(x-1)^2/2! + f'''(1)(x-1)^3/3! + ...

Since f(x) = e^2x, we have:

f(1) = e^2(1) = e^2

f'(1) = 2e^2(1) = 2e^2

f''(1) = 4e^2(1) = 4e^2

f'''(1) = 8e^2(1) = 8e^2

Substituting these values into the Taylor series formula, we get:

Taylor series: f(x) = e^2 + 2e^2(x-1) + 4e^2(x-1)^2/2! + 8e^2(x-1)^3/3! + ...

This is the Taylor series for f(x) = e^2x at x = 1.
