A function that crosses the x-axis at -2, crosses the x-axis at 1, and crosses the x-axis at 4. (Note that the vertical and horizontal scales are not the same.) Find the formula for the graph above, given that it is a polynomial, that all zeros of the polynomial are shown, that the exponents of each of the zeros are the least possible, and that it passes through the point (−1,−20)

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
