Use the information about the camera shown here to answer the question below. Turning the control dial reveals the following shutter speeds: 2,000, 1,000, 500, 250, 125, 60, 30, 15, 10, 8, 6, and 3. The reciprocal of each of these numbers is the length of time the shutter stays open to let light into the film. 1 seconds. The fastest opening for this camera is 250 1 For example, 250 is a shutter speed of 2,000 seconds. For lengths of time longer than those in the preceding list, there is a different system of numbers that enables shutter openings of up to 30 seconds. If a shutter speed of 250 doesn't allow quite enough light, the control dial should be set on what number?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
