Explain what the notation f(4)=100 means?
We could also say that when x=___, y=___?
in most functions, the expression f(x) can be written as y
So ....
x=4?
y=100?
Is That Right?
The notation f(4) = 100 means that when the input or independent variable, represented as 'x', is equal to 4, the output or dependent variable, represented as 'y' or 'f(x)', is equal to 100. In other words, it is stating that the function f, when evaluated at x = 4, yields a value of 100.
To understand this notation further, it helps to have knowledge of functions. A function is a mathematical relationship that assigns a unique output value to each input value. In this case, f is the name of the function, and the number inside the parentheses (4) represents the input or value of x. The result or output corresponding to this input is expressed after the equal sign, which in this case is 100.
To determine the values of x and y when f(4) = 100, we are given that x = 4 and y = 100.
