What is the domain of the function xx-4 equals 4?
It is difficult to say because of uncertainty as to what xx-4 represents. x2 - 4 = 4 gives x2 = 8 so x = ± 2*sqrt(2)
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
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.
8 - 2x - xx?
6
What is another name for the root of a function?
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.
What are the zeros of a polynomial function?
the zeros of a function is/are the values of the variables in the function that makes/make the function zero. for example: In f(x) = x2 -7x + 10, the zeros of the function are 2 and 5 because these will make the function zero.
What is the zero of a function and how does it relate to the functions graph?
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.
What is the domain of the function xx-4 equals 4?
It is difficult to say because of uncertainty as to what xx-4 represents. x2 - 4 = 4 gives x2 = 8 so x = ± 2*sqrt(2)
Domain of function?
The domain of a function encompasses all of the possible inputs of that function. On a Cartesian graph, this would be the x axis. For example, the function y = 2x has a domain of all values of x. The function y = x/2x has a domain of all values except zero, because 2 times zero is zero, which makes the function unsolvable.
What is a zero of a quadratic function?
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.
How do you integrate periodic functions?
Same as any other function - but in the case of a definite integral, you can take advantage of the periodicity. For example, assuming that a certain function has a period of pi, and the value of the definite integral from zero to pi is 2, then the integral from zero to 2 x pi is 4.
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.
Where does a function equal zero?
If you set a function equal to zero and solve for x, then you are finding where the function crosses the x-axis.
What does the root zero of a quadratic tell you?
It tells you where the function intersects the x-axis. In f(x)=x^2-4, 2 is a zero because when x=2, f(x)=0.
What is called when the denominator is zero in a rational function?
The function is not defined at any values at which the denominator is zero.
