How does the graph of f(x) = 5
cos 1/2 x

The graph of is a vertical stretch of 5 units and a horizontal stretch by 2 units of the parent graph

Step-by-step explanation:

We want to find out how the graph of compare with the graph of the parent function .

We can observe that the transformation applied to the basic cosine function is of the form:

The is a vertical stretch by a factor of 5 units.

is a horizontal stretch by a factor of 2 units.

Therefore the graph of  will stretch vertically by a factor of 5 units and stretch horizontally by a factor of 2 units as compared to  .

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26
