Determine the interval(s) on which the function is (strictly) increasing.

write your answer as an interval or union of intervals.
click on "none" if applicable.

points on graph:
(-6,1), (-3,6), (-1,2), (3,2), (4,4), (6,4)

The intervals that increase are

Interval 1 (-6,1), (-3,6)

Interval 2 (3,2), (4,4)

Step-by-step explanation:

Watching the graph, we have 5 intervals

(-6,1), (-3,6) increase

(-3,6), (-1,2) decrease

(-1,2), (3,2) constant

(3,2), (4,4) increase

(4,4), (6,4) constant

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
