Evaluate f(2) for f(x) = (2x + 3)/(x - 1).

Explanation:
To evaluate a function at a specific input, substitute that value for x and simplify. For f(x) = (2x + 3)/(x − 1) and x = 2: f(2) = (2·2 + 3)/(2 − 1) = (4 + 3)/1 = 7. The denominator isn’t zero here (2 − 1 = 1), so the expression is well-defined, and the value is 7.
