Set 3: Quadratic Equations (Intermediate)

Explanation

Answer: A

Which inequality represents the region below the parabola $y = x^2$ ?

$y < x^2$

✓ Correct

$y > x^2$

$y \leq x^2$

$y \geq x^2$

Detailed Explanation

Choice A is correct. Choice A is the correct answer. * $y = f(x)$ is the boundary line. * $y > f(x)$ is the region above. * $y < f(x)$ is the region below. Choice B is incorrect because it is above. Choice C is incorrect because it includes the boundary (usually 'below or on'). Choice D is incorrect because it is above or on.

Key Steps:

•

The correct answer is $y < x^2$

Why others are wrong:

B: Choice B is incorrect and may result from a calculation error.

C: Choice C is incorrect and may result from a calculation error.

D: Choice D is incorrect and may result from a calculation error.
