What is an example of a function with answer?

An example of a simple function is f(x) = x². In this function, the function f(x) takes the value of “x” and then squares it. For instance, if x = 3, then f(3) = 9. A few more examples of functions are: f(x) = sin x, f(x) = x² + 3, f(x) = 1/x, f(x) = 2x + 3, etc.

What type of function is f/x )=- X?

The modulus function is represented as f(x) = |x|. The input value of 'x' can be a positive or a negative expression.

What is fx in math?

f(x) is the value of the function. m is the slope of the line. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane. x is the value of the x-coordinate. This form is called the slope-intercept form.

What does f x mean example?

more ... A special relationship where each input has a single output. It is often written as "f(x)" where x is the input value. Example: f(x) = x/2 ("f of x equals x divided by 2")

How do you write an FX function?

To write such function in function notation, we simply replace the variable y with the phrase f(x) to get; f(x) = 3x + 7. This function f(x) = 3x + 7 is read as the value of f at x or as f of x.

What is the formula for a function?

Functions are generally represented as y = f(x) and it states the dependence of y on x, or we say that y is a function of x.

What is a function formula?

Function defines the relation between the input and the output. Function Formulas are used to calculate x-intercept, y-intercept and slope in any function. For a quadratic function, you could also calculate its vertex. Also, the function can be plotted in a graph for different values of x.

What does solve for f X mean?

f(x) means function of x. For x any number, f(x) depends on the value of x. Example: If f(x) = x + 2 and x = 6 then f(x) or f(6) = 6+2 = 8. Example: If f(x) = x^2 -1 and x = 5 then f(5) = 5^2 -1 =25 -1 = 24.

Is f/x )= 3x² a function?

No, it is a quadratic function. An exponential function has the variable as the exponent.

Is FX the same as Y?

An equation is a relationship between variables. Yes, y=x+3 and f(x)= x+3 yield the same results, which is why we teachers always tell you to remember that 'y and f(x) are the same thing'.

What function is x³?

The "basic" cubic function, f(x)=x3 , is graphed below. The function of the coefficient a in the general equation is to make the graph "wider" or "skinnier", or to reflect it (if negative): The constant d in the equation is the y -intercept of the graph.

What is the domain of f x )-?

Explanation: The domain of f(x) is all the values of x for which f(x) is defined. f(x) has no square roots or denominators, so it will always be defined; there are no restrictions on x because any and all values will lead to a real result. Therefore, the domain is the set of all real numbers.

Is f/x )= x³ an exponential function?

The function p(x) = x3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3x is an exponential function; the variable is the exponent.
