Let me analyze the image and break down the question.

The problem asks us to evaluate several definite integrals using the graph of $g(x)$. The graph is piecewise linear, with distinct segments across different intervals.

Here’s the plan:

1. Determine the shape areas (triangles, rectangles, etc.) under the curve $g(x)$ for each interval.

   • Positive areas (above the x-axis) contribute positively.
   • Negative areas (below the x-axis) contribute negatively.

2. Calculate each integral step by step and match the results to the expressions.

Let me calculate these values. sympy import symbols, integrate, Piecewise

Define the variable and the function g(x) as a piecewise linear function

x = symbols('x')

Defining the piecewise function from the graph

g = Piecewise( ((x + 4), (-6 <= x) & (x < -2)), # Line from (-6, -2) to (-2, 2) (2, (-2 <= x) & (x < 0)), # Constant line y=2 from (-2, 0) (2 - x, (0 <= x) & (x < 2)), # Line from (0, 2) to (2, 0) (-1, (2 <= x) & (x < 4)), # Constant line y=-1 from (2, 4) ((x - 5), (4 <= x) & (x <= 6)) # Line from (4, -1) to (6, 1) )

Integrals based on given ranges

integrals = { "a": integrate(g, (x, -1, 4)), "b": integrate(g, (x, -1, 0)) + integrate(g, (x, 0, 1)), "c": integrate(g, (x, -1, 6)), "d": integrate(g, (x, 4, 6)), "e": integrate(g, (x, -6, 6)), "f": integrate(abs(g), (x, -6, 6)), "g": integrate(g - 15, (x, -6, 6)) }

integralsHere are the results of the integrals based on the graph:

1. $\int_{-1}^{4} g(x) \, dx = 2$
2. $\int_{-1}^{0} g(x) \, dx + \int_{0}^{1} g(x) \, dx = \frac{7}{2}$
3. $\int_{-1}^{6} g(x) \, dx = 2$
4. $\int_{4}^{6} g(x) \, dx = 0$
5. $\int_{-6}^{6} g(x) \, dx = 4$
6. $\int_{-6}^{6} |g(x)| \, dx = 13$
7. $\int_{-6}^{6} (g(x) - 15) \, dx = -176$

Let me know if you'd like a detailed explanation for any of these calculations or clarifications on the integral process!
