Question

Which attributes of a quadratic
function are easiest to identify
from vertex form?

Answer 1

From the vertex form of a quadratic function, the vertex and the direction of the parabola are the easiest attributes to identify, as they are clearly represented in the equation.

Step-by-step explanation:

The easiest attributes to identify from a quadratic function in vertex form are the vertex and the direction of the parabola. The vertex form of a quadratic function is written as f(x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. The coefficient 'a' determines the direction of the parabola, where a positive 'a' means the parabola opens upwards and a negative 'a' indicates it opens downwards. Additionally, the absolute value of 'a' affects the width of the parabola; a larger value of |a| leads to a narrower parabola, while a smaller value of |a| leads to a wider parabola.
