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. See if you can guess what the third derivative is, or ... The subset of elements in Y that are actually associated with an x in X is called the range of f. Since in this video, f is invertible, every element in Y has an associated x, so the range is actually equal to the co-domain. So yes, Y is the co-domain as well as the range of f and you can call it by either name.y is a variable, while f (x) means "the value that f maps x to"; the equation y=f (x) could be read as "y equals the value that f maps x to" or more succinctly as "f maps x to y". 1. [deleted] • 5 yr. ago. On the graph of a function, y and f (x) are very much the same thing. Every point on the graph of f (x) has coordinates:The process of finding a potential function of a conservative vector field is a multi-step procedure that involves both integration and differentiation, while paying close attention to the variables you are integrating or differentiating with respect to. For this reason, given a vector field $\dlvf$, we recommend that you first determine that that $\dlvf$ is indeed …Web

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.
