Answer:
Step-by-step explanation:
given that an article in the Sacramento Bee (March 8, 1984, p. A1) reported on a study finding that "men who drank 500 ounces or more of beer a month (about 16 ounces a day) were three times more likely to develop cancer of the rectum than non-drinkers."
To support this some data collected should be given. The data should be from a sample of a large size randomly drawn from 2 groups one men who drank 500 oz or more of beer and other group not drank that much. These people medical history with cancer patients number also should have been given.
Non proportional you can see by the way the graph is
I see y = 3x^2 - 2. If that is the case, there is no movement indicated in the x direction at all, only the y direction. If there was movement along the x axis, there would be a number inside a set of () with the x, like this: (x-3)^2. But that is not there in your case, so the x coordinate of the vertex stays right where it starts, at the origin, or x = 0. The "minus 2" indicates y movement: down 2 units. So the vertex sits at (0, -2). The axis of symmetry is the same as what the x coordinate is, but in equation form. So the axis of symmetry has an equation of x = 0.
