Question

Choose the function whose graph is given by: 3 +2 ent wt + 1 i الت 3 ti A. y = cos(x + 2) O B. y = sin x + 3 = O C. y = cos x + 3 D. Y = COS X + 2

Answer 1

Given:-

A graph.

To find:-

Which function suits the graph.

In the option the fuction consist of sin and cos.

Defnitly sin cannot be the graph since the graph of the sin start at the orgin and go upwards but here the graph goes downwards so sin can not be the graph.

So the graph is of cos.

For cosx the graph lies at the point 1 at the y axis but here in the graph the point is 3 at the y axis, that is 2 more that cosx.

So the graph is Cosx+2.

So the correct option is OPTION D.
