The given graph respresents the function of y = 2cos(2x)+1
What is a graph?
A graph can be defined as a pictorial representation or a diagram that represents data or values.
From the given graph we can pick the points which can tell us about the nature of the cosine function we took,
It is clear from the graph that the function plotted is 2 times greater than the standard function i.e. cos (x)
In cos (x) ⇒ we have maxima at (0, 1)
in the graph, ⇒ we have maxima at (0, 3)
there is a change in the graph concerning the standard cos graph.
Hence, the graph given is 2cos(2x)+1
2cos(2x)+1 is the function represented in the graph.
