**2. Consider the function \( f(x) = 3x - 2 \) on \([1,5]\).**

(a) By interpreting \(\int_1^5 3x - 2 \, dx\) as net area, compute the value of this integral. Generate a graph of this function and draw the region described by the integral. Use the Fundamental Theorem of Calculus to compute this integral.
