f(x)= -x^2 + x^-1
f(-2)= - (-2)^2 + (-2)^-1 = -4 - 1/2 = -9/2
f(-1)= - (-1)^2 + (-1)^-1 = -1 -1 = -2
f(1) = - (1)^2 + (1)^-1 = -1 +1 = 0
The range is { -9/2, -2, 0}
You got these prime numbers from a factor tree you need to multiple them together to get 2475
The answer rounded would be .83. I got this by writing out the equation each hour. For example, 1/2+1/2+1/2+1/2+6+1/2+1/2+1/2+1/2+0+0+0 = 10. Then, to find the average you divide them out by the amount of numbers. This would give you 10 divided by 12.
