Question

Graph y=-4cos(x)+3 in the interactive w ote that one moveablepoint always defines an ext d the other point always defines a neighbouring in

Answer 1

The graph of the function y = -4cos(x) + 3 is added as an attachment

How to sketch the graph of the transformed function

From the question, we have the following parameters that can be used in our computation:

y = -4cos(x) + 3

The parent function of the above is

y = cos(x)

The function y = -4cos(x) + 3 is a cosine function that has been transformed as follows

Reflected across the x-axis

This gives

y = -cos(x)

Vertically stretched by a factor of 4

This gives

y = -4cos(x)

Shifted up by 3 units

This gives

y = -4cos(x) + 3

Next, we plot the graph using a graphing tool by taking not of the above transformations rules
