F(x) = 2x g(x) = 2x + 1 Find (4) (a).

Include any restrictions on the domain.

A. (2) 22+1 2.0 ,2 > 0
B. (x) = 2x+1, X + - 1 2
c. (x) 32. 2x+1 x = -2 9 2x+1
D. ( x + 0 2.2, 3

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.
