A zero of a function is the value of the independent variable which makes the value of the function equal to zero. Sometimes called a root of the function, as well.
Example: f(x) = x - 3. The value of x, which makes f(x) = 0 is x = 3, so the zero of the function is x=3.
For f(x) = x2 - 9: The values, {x=3 and x=-3} both are zeros of this function.
To make it more simple, when looking at a graph, the zero is where your function crosses or touches the x-axis. These are REAL zeros. Sometimes, however, the zero might be an imaginary number. You cannot see it on the graph. So you have to work out the problem to determine ALL POSSIBLE zeros.

Where is the zero of any function location on the coordinate plane?
The zero of a function is a point where the function evaluates to zero. If you express "y" as a function of "x", i.e. y = f(x), then for a zero of the function, the y-coordinate is 0. In other words, the corresponding point is on the x-axis.
Are there any math words that start with a z?
a zero matrix,zero of a function and a zero slope
What is the derivative of the the constant function?
zero
Can a logarithmic function have a base of zero?
No. No number can be generated by raising zero to a power. Zero raised to any power is still zero.
Why do you equate the equation to zero?
Not all equations are equated to zero, but usually we set a function equal to zero if we want to find its x intercepts, or where the graph of the function crosses the x axis.
