What is "if f(x) = startfraction x over 2 endfraction + 8?

This is a mathematical function that takes a variable x and computes a value based on the formula f(x) = x/2 + 8.

This function represents a linear relationship between the input variable x and the output value f(x). The function divides x by 2 and then adds 8 to the result.

For example, if we input x = 10 into the function, we would calculate f(10) = 10/2 + 8 = 5 + 8 = 13. So the output value for x = 10 would be 13.

This type of function is useful for modeling relationships where the output value is dependent on the input value in a simple, linear way.
