Evaluating Function Notation Calculus | If f(x)=x²-4x, find (a) f(-5), (b) f(y²+1) (c) f(x+1)-f(x-1)

What is f(x)? It is different way of writing "y" in equation, but it is more useful. A basic description of a functon notation and a few examples involving function notation.

If I am right po, your source is from diff & integ cal. from feliciano and uy book, if I may ask, how do you solve the problem if the f (x+Δx). Thanks if you reply.

Hi po, paano mo po nakuha yung 2y sa f(y²+1)?

Pano naman po kung ∆ may ganyan siyang symbol?

f(x+∆x)
