For this subject you need visualize that the shape with an extra shape attached is cut off and so multiply the numbers to find the area for the compound shapes I think and the. You add them all up so you need to add the initial symbols such as cm or sq whatever’s you need to insert if this is wrong search on the web
The answer is 3. -2i square root of 2
Answer:
x<-4
Step-by-step explanation:

The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
<h3>How to determine the graph of the function f(x)=4sin(2πx)?</h3>
The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)
