Set 12: Linear Inequalities

Choice A is correct. Choice A is the correct answer. Visualize the regions. 1. $y > x^2$: Region "inside" or above the parabola opening up. 2. $y < 4$: Region below the horizontal line $y=4$. 3. Intersection: The bowl-shaped region bounded below by the parabola and above by the line. Strategic Tip: $y > f(x)$ is above the graph, $y < f(x)$ is below. Choice B is incorrect because outside/below the parabola is $y < x^2$. Choice C is incorrect because above $y=4$ is $y > 4$. Choice D is incorrect because the regions clearly overlap (e.g., point $(0, 1)$ works).
