What are the domain and range of the function f(X) = 5^x-3+1? domain: all real numbers greater than 1
range: all real numbers

domain: all real numbers
range: all real numbers areater than 0

domain: all real numbers
range: all real numbers greater than 1

domain: all real numbers greater than 5
range: all real numbers greater than 1

Add up all the sides

(6,0) i hope it makes enough sense

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.
