Add a comment. 1. if you sub y = −x, y = − x, you get. 0 = f(0) = f(x − x) = f(x) + f(−x) −x2 (1) (1) 0 = f ( 0) = f ( x − x) = f ( x) + f ( − x) − x 2. suppose further assume that f = ax2 + bx. f = a x 2 + b x. subbing in (1), ( 1), gives you f = 1 2x2 + bx f = 1 2 x 2 + b x for any b. b.

The inverse of a function f is a function f^ (-1) such that, for all x in the domain of f, f^ (-1) (f (x)) = x. Similarly, for all y in the domain of f^ (-1), f (f^ (-1) (y)) = y. Can you always find the inverse of a function? Not every function has an inverse. A function can only have an inverse if it is one-to-one so that no two elements in ...

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 everywhere, so f' (x) = 5. Then f'' (x) is the slope of a horizontal line--which is 0. So f'' (x) = 0.
