Question

sophia plots points on a graph to represent the shape of a concave lens. which type of function should sophia use to model the shape of the lens? linear exponential quadratic square root

Explanation:

Step1: Recall function - shape characteristics

Linear functions are straight - lines. Exponential functions have a rapid growth or decay curve. Square - root functions have a half - parabola shape. Quadratic functions have a parabolic shape.

Step2: Analyze the shape of a concave lens

The shape of a concave lens is parabolic. A quadratic function \(y = ax^{2}+bx + c\) (\(a
eq0\)) has a parabolic graph.

Answer:

quadratic
