Set 17: Quadratic Equations (Intermediate)

Choice A is correct. Choice A is the correct answer. In standard form $y = ax^2 + bx + c$, the y-intercept is always the constant term $c$. 1. Here $c = 8$. 2. So the y-intercept is 8 (or the point $(0, 8)$). Choice B is incorrect because of sign error. Choice C is incorrect because it is $b$. Choice D is incorrect.
