Final answer:
To find the total area between the curve and the x-axis, you need to calculate the area of the shaded regions. The correct answer choice is option (c) Perform the necessary calculations.
Step-by-step explanation:
To find the total area between the curve and the x-axis, we need to calculate the area of the shaded regions by estimating shapes over smaller intervals. Since the question mentions a graph, we can sketch the curve and shade the region between $x = 2.3$ and $x = 12.7$. Then, we can calculate the area of the shaded region using a calculator or similar tool to get a sufficiently accurate estimate.
Option (c) Perform the necessary calculations is the correct answer choice for this question.
