Function defined for all real numbers
WebThe function is defined for all real numbers. So, the domain of the function is set of real numbers. As x tends to ∞ , the value of the function tends to zero and the graph approaches x -axis but never touches it. As x tends to − ∞ , the function also tends to ∞ . WebSubtracting Two Functions. For subtracting two real functions let us define the functions f and g such that f: X R and g: X R are two real functions such that X is a subset of R. …
