C. -7.25 + 0.5(n)
Let's plug in some numbers
Let n = 2
-7.25 + 0.5(2) = -6.25
Let n = 3
-7.25 + 0.5(3) = -5.75
All the numbers match up when you substitute a whole number, therefore it is C.
Let's check one last one, if n=4
-7.25 + 0.5(4) = -5.25
Let's check to see if this is true.
-5.75 - 0.5 = -6.25
The -5.75 and the -6.25 are all numbers given for the equation. (in your picture)

Determine the domain of the function.<br><br> f(x)=4/x^2
harkovskaia [24]
Since x can be any value as long as the denominator equals 0 (it doesn't matter if it's positive or negative), we have to figure out when x^2=0, which is when x=0. Therefore, the domain is (-inf, 0) U (0, inf)
