Choose correct graph with following function

Mathematics
1 answer:
Vlad1618 [11]3 years ago
4 0

Answer:

The answer to your question is The second graph

Step-by-step explanation:

The general equation for a trigonometric is

                        Acos(Bx + C) + D

A indicates the amplitude if the value is 1, the lowest point is -1 and the highest point is 1.  So we discard the first graph.

B indicates the period. A normal graph has a period of 2π, but this equation has a period of 3/2. This means that the period is smaller.

C indicates that the graph is moved to the left or right but in this problem C = 0, so it does not change.

D indicates if the graph is moved up or down, in this problem, D = 0 so it does not change.

Simplify -4 + (-3) + 6
Sedaia [141]
Start off with: -4 + (-3) + 6

First of all, when there is a, + sign and a - sign next to each other, the - side wins.
E.g. 1 +- 3 = 1 - 3

So, apply this to our one:
-4 -3 +6

From there you solve, you can do this using the number line method or whatever you are into:
=-7 + 6
=-1
The answer is -1
