# Please i have a question about Machine learning what Does f and x mean

f(x) = tanh(x) = sinh(x)/cosh(x) = e^x-e^-x/e^x+e^-x

f(x) is a function and x is the input value

example:
f(x) = 4x + 3
f(3) = 4(3) + 3
f(3) = 12 + 3
f(3) = 15
where 3 is the value and f(x) is the function

Learning a Function
Machine learning algorithms are described as learning a target function (f) that best maps input variables (X) to an output variable (Y). Y = f(X) This is a general learning task where we would like to make predictions in the future (Y) given new examples of input variables (X).

What is a function

Ultra WALKER think of a function as a machine that takes in an input and throws out an output based on the input.

F is a function. Functions is sequence of calculates. X is a number which you pass in a function
