Is the function shown in the graph one-to-one?

No, there exists more than one output for at least one input.

Yes, there exists one output for every input.

Yes, there exists one input for every output.

No, there exists more than one input for at least one output.

Yes, there exists one output for every input.

Step-by-step explanation:

A function is called one-to-one if every output(y)comes from one kind of  input(x) . There are no two input that give same output.

To know if a function is one-to-one you can do vertical line test. Draw vertical lines on several points and see if there are 2 point intersect with the lines. From the graph, you can see that it pass horizontal lines test.

On other hands, if every input give only 1 kind of output is the graph will be called as a function. This can be tested using vertical line test. This graph is also a function.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.
