Math Problem Statement

using the images for info, can you guess the formula for f'(x) = 2^x

Using the image, can you guess the formula for f'(x) = 2^x?

Solution

The image shows the graph of the exponential function f(x)=2xf(x) = 2^x, and you are asking for the derivative, f(x)f'(x).

To differentiate f(x)=2xf(x) = 2^x, we use the chain rule and the fact that the derivative of axa^x (for any base aa) is given by: ddx(ax)=axln(a)\frac{d}{dx}(a^x) = a^x \ln(a) where ln(a)\ln(a) is the natural logarithm of the base aa.

In the case of f(x)=2xf(x) = 2^x, the derivative is: f(x)=2xln(2)f'(x) = 2^x \ln(2)

Thus, the derivative of f(x)=2xf(x) = 2^x is f(x)=2xln(2)f'(x) = 2^x \ln(2).

Would you like further explanation or have questions about this?

Here are 5 related questions to expand on the concept:

  1. How do you differentiate more complex exponential functions like 3x3^x?
  2. What is the difference between differentiating 2x2^x and exe^x?
  3. How does the graph of the derivative f(x)=2xln(2)f'(x) = 2^x \ln(2) compare to the graph of f(x)=2xf(x) = 2^x?
  4. Can you explain the chain rule in detail when applied to functions like 2x2^x?
  5. How do logarithmic functions relate to the differentiation of exponential functions?

Tip: When differentiating exponential functions with bases other than ee, always remember to multiply by the natural logarithm of the base!
