Determine wether the function is increasing, decreasing, or constant

Mathematics
1 answer:
evablogger [386]2 years ago
4 0

Answer:

decreasing

Step-by-step explanation:

"Increasing" means the graph is going up from left to right.

"Decreasing" means the graph is going down from left to right.

"Constant" means the graph is "flat" (this is not a technical term) it is keeping the same y value, neither going up nor going down.

What can be super confusing is the

(2.2, 5) mentioned in the question. THIS IS NOT A POINT. It is an interval and points and intervals unfortunately have the same notation sometimes.

An "interval" is a section of the graph, here: FROM 2.2 not including 2.2, TO 5 not including 5. These are like the address on the x-axis. If you look at your graph at 2.2 on the x-axis, it is a peak(relative maximum) and it goes down to the right to where x is 5 where it bottoms out (relative minimum) So on that interval, from 2.2 to 5, the graph is DECREASING.

Write the expression as the sine, cosine, or tangent of an angle.
erma4kov [3.2K]

Answer:

tan56°

Step-by-step explanation:

The Addition identity for tangent ratio is

tan(x + y) = \frac{tanx+tany}{1-tanxtany} , thus

\frac{tan24+tan32}{1-tan24tan32} = tan(24 + 32)° = tan56°
