The given demand curve is Q = 25 - 0.5 P. To obtain the revenue curve, express price P as a function of quantity Q and then multiply by Q.

Step 1: Solve for P in terms of Q.
From Q = 25 - 0.5P, rearrange: 0.5P = 25 - Q, so P = 50 - 2Q.

Step 2: Revenue as a function of Q.
Revenue R(Q) = P × Q = Q(50 - 2Q) = 50Q - 2Q^2.

Step 3: Shape and key properties of the revenue function.
- It is a downward-opening quadratic (coefficient of Q^2 is -2), so the revenue curve is concave down.
- The vertex of R(Q) = 50Q - 2Q^2 occurs where dR/dQ = 50 - 4Q = 0, so Q* = 50/4 = 12.5.
- Maximum revenue at Q = 12.5 is R(Q*) = 50(12.5) - 2(12.5)^2 = 625 - 312.5 = 312.5.
- The revenue is zero at Q = 0 and at Q = 25 (since P = 50 - 2Q becomes zero when Q = 25, giving R = 0).

Step 4: How the correct graph should look.
- The curve starts at (Q, R) = (0, 0).
- It rises to a maximum around Q = 12.5 with R ≈ 312.5.
- It falls back to (Q, R) = (25, 0).
- Between these points, the curve is a smooth, symmetric downward-opening parabola.

Given that the options are not provided (the answer choices appear empty), you cannot definitively select which graph corresponds to R = 50Q - 2Q^2 without seeing the graphs. The correct graph, if present, would be the downward-opening parabola with vertex at Q = 12.5 and maximum revenue ≈ 312.5, passing through (0,0) and (25,0).

A firm has a demand curve of 𝑄 = 25 − 0.5 𝑃 . Which of the following is the correct revenue curve for this firm? Note that the horizontal axis on each graph is quantity and the vertical axis is revenue. 单项选择题
