It means the value of the function equals zero when the argument is 4.
For example:
f(x)=x-4
f(4)=4-4=0

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.
If you meant x + 5 = 4 then the multiplicity is 1.

zero
The "root" of a function is also called the "zero" of a function. This is where the function equals zero. The function y=4-x2 has roots at x=2 and x=-2 The function y=4-x2 has zeroes at x=2 and x=-2 Those are equivalent statements.
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.

The "zero" or "root" of such a function - or of any other function - is the answer to the question: "What value must the variable 'x' have, to let the function have a value of zero?" Or any other variable, depending how the function is defined.
(x + 2)(x + 4) x = -2, -4
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.
If you set a function equal to zero and solve for x, then you are finding where the function crosses the x-axis.
If you mean y = -3x-4 then it is the function of a straight line equation
The function is not defined at any values at which the denominator is zero.
A polynomial is identically equal to zero if and only if all of its coefficients are equal to zero. eg. The power series on the left is identically equal to zero, consequently all of its coefficients are equal to 0:
Yes. So long as the function has a value at the points in question, the function is considered defined.
If you meant x + 5 = 4 then the multiplicity is 1.
