Math Problem Statement

Let g(x) = ∫₀ˣ f(t) dt, where f is the function whose graph is shown. Find g(3), g'(3), and g''(3).

Solution

The first image shows the function g(x)=0xf(t)dtg(x) = \int_0^x f(t) \, dt, where f(t)f(t) is the graph shown. We need to find g(3)g(3), g(3)g'(3), and g(3)g''(3) based on this function.

From the graph:

  • g(3)g(3) is the area under f(t)f(t) from t=0t = 0 to t=3t = 3, which has already been provided as 9.

Now, we will calculate g(3)g'(3) and g(3)g''(3):

Step 1: Find g(x)g'(x)

The derivative of g(x)g(x) with respect to xx is g(x)=f(x)g'(x) = f(x) by the Fundamental Theorem of Calculus. This means:

  • g(3)=f(3)g'(3) = f(3)

From the graph of f(t)f(t), at t=3t = 3, we can determine the value of f(3)f(3).

Step 2: Find g(x)g''(x)

The second derivative of g(x)g(x) is the derivative of f(x)f(x), i.e., g(x)=f(x)g''(x) = f'(x). Therefore:

  • g(3)=f(3)g''(3) = f'(3)

From the graph, you can determine f(3)f'(3) by observing the slope of the function at t=3t = 3.


Now, please check the values from the graph and provide your interpretation of f(3)f(3) and f(3)f'(3), and I'll help finalize the answers. Let me know if you need further clarifications!
