We say A is a function of r. Our input in this example is r, or the radius. The output is πr2, or what the actual area is. How function notation works is whatever number you see as the input, you substitute that into the equation for the respective variable. A(5)=π(5)2A(5...
Function notation is a compact form used to express the dependent variable of a function in terms of the independent variable. Using function notation, y is the dependent variable and x is the independent variable. The equation of a function is y = f(x...
Function notation gives a name to a function, and makes clear which variable is independent (that is, which is the variable for which you'll be picking input values). The name for the formula, such asA(for, say, the area of a square), is followed by a parenthetical, such as(s)(for...
The notation for function operations is the same as the notation for number (that is, arithmetical) operations:addition: (g + h)(x) = g(x) + h(x) subtraction: (g − h)(x) = g(x) − h(x) multiplication: (g× h)(x) = g(x)× h(x) division: (g÷ h)(x) = g(x...
In mathematics, a function is typically represented using notation, such as "f(x)", where "f" is the name of the function and "x" is the input variable. The function can be defined explicitly, with a direct expression or formula, or implic...

The perimeter of the rectangle is given by the equation 2l + 2w = p.Jim and his dad want to find the length of the garden once they decide its width. I need to use function notation to write a function that represents its length in terms of the width....
why might function notation be important? Suppose that x = x(t) and y = y(t) are both functions of t. If y^2 +xy-3x = -21,\space and \space \frac{dy}{dt} = 4 when x = 5 and y = -3, what is \frac{dx}{dt}? a. Explain the words "relation" and "function". Includ...
When we say the solution set is anywhere between 3 and 4, then one might argue that if we are talking about integers, there are no integers in the given range. But, if we talk about the real numbers the situation is a little different. We notice that that are infinite numbers in the...
