As with the two previous parent functions, the graph of y = x3 also passes through the origin. Its domain and range are both (-∞, ∞) or all real numbers as well. Absolute Value Functions The parent function of absolute value functions is y = |x|. As shown from the parent function...
Let f and g be functions that are differentiable for all real numbers x and that have the following properties.(i) f'(x)=f(x)-g(x)(ii) g'(x)=g(x)-f(x)(iii f(0)=5(iv) g(0)=1Prove that f(x)+g(x)=6 for all x....
