Answer:
we can draw the graph of cosine with amplitude 2.
Step-by-step explanation:
In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.
Its a cosine graph given in the form of y = acos(Bx + c) + d
Here a is amplitude, period = , c = phase shift, d = vertical shift
We know a = 2, B = , c = 0, d = 0.
First find the value of m by solving the inequality.
Solving the inequality we get value of m: m>-4
Now, for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
Step-by-step explanation:
We need to draw the graph of the solution set for the following inequality.
First we will solve the inequality and find value of m
Adding -18 on both sides
Dividing both sides by -3 and reversing the inequality i.e < is changed into >
So, value of m is: m>-4
So. for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
The graph is shown in figure attached.
