Author: Joseph Baxter. Linear, quadratic and exponential functions have different graphs, equations, and characteristics. In this tutorial, compare the shape of linear, quadratic, and exponential curves on a graph, and explore how to identify a function as linear, quadratic, or exponential by examining x- and y-coordinates.

The tier of cells at the back of the retina contains the light receptors, the rods and cones. Rods, which are far more numerous than cones, are responsible for our vision in dim light and are out of commission in bright light.
retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well- lit conditions. The cones detect fine detail and give rise to color sensations EX-sunny, spring day: photoreceptors: convert light energy to electrochemical neural impulses. EX-Both rods and cones are the photoreceptors: dark adaptation
