A cross-section is the shape that would be exposed when cutting straight through a 3-D object. for example, cutting horizontally through a regular cone would expose a circle.
an intersection is where 2 or more shapes (does not matter how many dimensions) overlap. for example, the point at which two lines overlap is the intersection. or the area that two overlapping circles share is the intersection.
Answer:
B
Step-by-step explanation
a function has to be on a graph and pass the horizontal line test. if it does not pass it then it will not be a function
Answer:
f(0)=6
Step-by-step explanation:
When representing function's values by set of ordered pairs, the first one correspond to the x value and the second to the image or "y" value.
When you read f(0) means "when x is 0" then the 6 is the value of the function or the image.
Answer:
43.96
Step-by-step explanation:warning might be wrong
1) First is an odd function because f(-x)=-f(x)
3) 3d is an even function because f(-x)=f(x)
2) 2d looks like sin function and it is also odd.
