which of the following best describes interval b on the graph shown?

a coordinate plane is shown. a line is horizontal from x equals 0 to 2, increases from 2 to 4, decreases from 4 to 5, and decreases at a slower rate from 5 to 8.

linear constant

linear decreasing

linear increasing

nonlinear increasing

It increased then decreases
not linear because it would be steadily decreasing or increasng at a constant rate (slope) if it was linear

answer is non linear increasing

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.
