How can an absolute value function extend below the x-axis?

  by translating or scaling the function

Step-by-step explanation:

The parent absolute value function f(x) = |x| does not extend below the x-axis. The graph of a translated (and/or scaled) version of the function may extend below the x-axis.

In the attachment, one function has simply been translated down 3 (and right 2) so that it extends below the x-axis. The other one has been scaled by a negative number, so it does not go above the x-axis.

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.

The total would be 40.53
