Given the function g(x)=x^2+10x+23g(x)=x
2
+10x+23, determine the average rate of change of the function over the interval -8\le x \le -4−8≤x≤−4.

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.
