WebMar 2, 2024 · Sorted by: 1. When you define a function f ( x) on its domain X, it means that for each x 0 ∈ X you know the value f ( x 0). In a similar sense, the derivative of a function f ( x) in X (if it's differentiable in X) is defined as f ′ ( a) for each a ∈ X, hence f ′ ( a) is a constant, but f ′ ( x) is a function on X. Share. WebSo f (x) shows us the function is called " f ", and " x " goes in. And we usually see what a function does with the input: f (x) = x2 shows us that function " f " takes " x " and squares it. Example: with f (x) = x2: an input of 4. becomes an output of 16. In fact we can write f (4) … On A Graph . So let us see a few examples to understand what is going on.

(x-2=0, which is x=2). When we set the denominator of g (x) equal to 0, we get x=0. So x cannot be equal to 2 or 0. Please click on the image for a better understanding.

WebJun 14, 2016 · No. They have no special significance. All of these are simply used by convention to refer to a function. For example, f(x)=e^x, a(x)=e^x, and z(x)=e^x all mean the same thing. However, some notations mean only one thing. For example, zeta(s) refers to the Riemann zeta function: sum_(n=1)^oo1/n^s (See this link for more info: Riemann … WebRemember that the value of f'(x) anywhere is just the slope of the tangent line to f(x). On the graph of a line, the slope is a constant. The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f(x) = 5x + 1, then the slope is just 5 …

WebJul 19, 2024 · Jake, the answer is No! f (f (x)) means replace each x in f (x) by the entire function f (x). For example, if f (x) = x 3 + 13x + 9, then f (f (x)) = (x 3 + 13x + 9) 3 + 13 (x 3 + 13x + 9) + 9. However, f 2 (x) would mean (f (x)) 2 so, in the above example, f 2 (x) = (x 3 + 13x + 9) 2.
