Which function has an inverse that is also a function? {(-4,3), (-2,7).(-1,0), (4, -3), (11, -7)}
{(-4, 6), (-2,2), (–1, 6), (4,2), (11, 2)}
{-4,5), (-2,9), (-1,8), (4,8). (11,4)}
{(-4,4), (-2,-1),(-1,0), (4, 1), (11, 1)}​

The answer is 15×7=105therefore, 105×5=525 miles

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.
