why are the domain and range of square root function restricted to [0,∞) ?

Expert Solution

Square root of negative numbers are complex numbers ,so there is no real root for negitive real numbers .square root of zero is zero and the square root of positive real numbers are real so the domain of square root is greater than or equal to 0. Therefore square root function domain= [0,∞)

write a function to determine the square root of a number. The square root of a number can be approximated by repeated calculation using the formula NG = 0.5(LG + N/LG) where NG stands for the next guess and LG stands for the last guess. The loop should repeat until the difference between NG and LG is less than 0.00001. Use an initial guess of 1.0. Write a driver program to test your square root function. I WANT THIS PROGRAM...

Let f be a function with domain the reals and range the reals. Assume that f has a local minimum at each point x in its domain. (This means that, for each x ∈ R, there is an E = Ex > 0 such that, whenever | x−t |< E then f(x) ≤ f(t).) Do not assume that f is differentiable, or continuous, or anything nice like that. Prove that the image of f is countable. (Hint: When I solved...

• The range of f is the domain of g and the domain of f is the range of g. • f(a) = b if and only if g(b) = a. • (a, b) is on the graph of f if and only if (b, a) is on the graph of g. The function f(x) = x3 + 7x + 5 is one-to-one. Since finding a formula for its inverse is beyond the scope of this textbook, use Properties of...

(6) Consider the function f(x, y) = 9 − x^2 − y^2 restricted to the domain x^2/9 + y^2 ≤ 1. This function has a single critical point at (0, 0) (a) Using an appropriate parameterization of the boundary of the domain, find the critical points of f(x, y) restricted to the boundary. (b) Using the method of Lagrange Multipliers, find the critical points of f(x, y) restricted to the boundary. (c) Assuming that the critical points you found were...
