What are the first five terms of the sequence defined by the given function? f(n) = 2n − 8

A.
2, 8, 14, 20, 26
B.
-6, -8, -10, -12, -14
C.
2, -4, -10, -16, -22
D.
-6, -4, -2, 0, 2

The correct answer is: b

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

Not sure what the question is but i hope this x = years100 * x
