Yes. In general, both the input and the output of a function can be zero.

A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
you have to first find the derivative of the original function. You then make the derivative equal to zero and solve for x.
It is sometimes the point where the value inside the absolute function is zero.
No.As you approach zero from the left, the value increases without bound. As you approach zero from the right, the value decreases without bound.
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.
