Given function f(x) = 2x5y = f(x) For x = 0 y = 5 For x = 1 y = 3 For x = 1 y = 7 Substtute x = 0,1,1 respectively, the value of y would be 5,3,7 x values are domain of the function In this case we can substitute any real number for x, we will get value of f(x) Domain of the function is all real numbers Interval notation is (∞,∞)So the curves intersect when x= 4 and x= 2Which equation is the inverse of 2(x 2)² = 8(7 y)?

Y=x^2 2x-8 domain-Question Given the function, f(x)= 2/x^22x3 find tthe domain and range by showing your work After that, find the x and y intercepts Answer by Fombitz() (Show Source) You can put this solution on YOUR website!The domain is where x 2 − 2 x − 8 is real, so the domain is x ≥ 4 or x ≤ 2 As for the range, if the square root function returns only the positive root, the range is y ≥ 0 To see this, note that 0 is in the range ( x = − 2 , x = 4 ) , that the function is continuous over the domain of x (so every y between the minimum and maximum is in the range), and the lim x → ∞ x 2 − 2 x − 8 = lim x → −

y = x2 2x −5 y is defined ∀x ∈ R Hence the domain of y is ( − ∞, ∞) y is a quadratic function of the form ax2 bx c The graph of y is a parabola with vertex where x = −b 2a Since the coefficient of x2 > 0 the vertex will be the absolute minimum of y At the vertex x = −2 2 × 1 = − 1 ∴ ymin = y( −1) = 1 − 2 − 5 = − 6Y(4) = 2 1 Rewriting the LHS in di erential form and factoring the RHS we get dy dx = (x 2)(y 1) (x 3)(y 1) 2 Separating the variables leads to y 1 y 1 dy = x 2 x 3 dx 3 To evaluate the integrals Z y 1 y 1 dy = Z x 2 x 3 dx we need usubstitution on both sides On the LHS, let u = y 1 and then du = dy View _jpg from MATH at University of California, Los Angeles ise 25 1 Find the inverse f of the function in each of the following a) y = 2x 8, Domain = (x x 24} b )

Chapter 2 21 Functions definition, notation A function is a rule (correspondence) that assigns to each element x of one set , say X, one and only one element y of another set, Y The set X is called the domain of the function and the set of all elements of the set Y that are associated with some element of the set X is called the range of the functionAnswer (1 of 3) Before actually answering your question, I assume that you are treating it as a function y depending on variable x ie y=log(2–2^x), where log has base 2 Since log is defined for 2–2^x>0 only which gives you 2^x What is the domain and range of, y=2x^28 What are the domain and range, y=x^28x16 What are the domain and range, y=2x^212x15 What are the domain and range, y=2x^ Categories Uncategorized Leave a Reply Cancel reply Your email address will not be published Required fields are marked * Comment
