Question

5. f(x) = x2/3

h(x)=x√x + 2
4+3 increasing
6. g(x) = -3
8. y = |x - 3| + x + 21

Answer 1

5. Decreasing: (-Infinity,0) and Increasing: (0,Infinity)

6. Stays Constant

7. Decreasing: (-2,-1.333) and Increasing: (-1.333,Infinity)

8. Decreasing: (-Infinity,-2) Constant: (-2,3) Increasing: (3,infinity)

Explanation:

put all equations in a graphing calculator to look at graphs. These questions are a little tricky since there can be more than one answer, but once you understand it should be easy!

5. Decreasing from -Infinity to 0 and Increasing from 0 to Infinity

6. Stays Constant because it is a straight line

7. decreasing from -2 to -1.333 and Increasing from -1.333 to Infinity

8. decreasing from -Infinity to -2, constant from -2 to 3, and Increasing from 3 to infinity
