Does anyone know what function value is and can someone show me an example? Thanks for helping
Here is an example.
If the function is f(x) = x+3 and the value of x is 1, then the function value is 1 + 3 = 4.
Function value is the result of evaluating a function at a particular input value. In other words, it is the value of the dependent variable when the independent variable takes on a specific value. To find the function value, you need to substitute the input value into the function and perform the necessary calculations. Here's an example to illustrate:
Let's say we have the function f(x) = 2x + 3. To find the function value for a specific input, we substitute that input into the function.
For example, if we want to find the value of f(4), we replace x with 4 in the function: f(4) = 2(4) + 3.
Then we simplify the expression: f(4) = 8 + 3 = 11.
Therefore, the function value of f(4) is 11.
In general, the process of finding the function value involves plugging in the input value into the function and evaluating it. This allows you to find the corresponding output value.
