The function f(x)=2/3x+2 can be formed by shifting the function y=2/3x in which way?
a. vertical shift down 2
b. horizontal shift to the right 2
c. vertical shift up 2
d. horizontal shift to the left

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.
