Answer:
If it cuts x-axis 5 times.
Step-by-step explanation:
When we look at the graph of a function we can see its real roots by looking at its graph
The intersecting points that is the number of times a line cutting x-axis will be the real root of the function
So, by looking at the 5th degree function the number of time that function cuts x-axis will be the number of real roots.
So, if we need to say all the zeroes or roots of the function are real means it will cut the x-axis 5 times.
Because a function will have the root equal to its degree.
