Finding range of a function algebraically

Web2. Algebraically: There is no set way to find the range algebraically. However, one strategy that works most of the time is to find the domain of the inverse function (if it exists). First, swap the x and y variables everywhere they appear in the equation and then solve for y. Find the domain of this new equation and it will be the range of the ...

4.7: Domain and Range of a Function - Mathematics LibreTexts

WebThe only problem I have with this function is that I cannot have a negative inside the square root. So I'll set the insides greater-than-or-equal-to zero, and solve. The result will be my domain: −2 x + 3 ≥ 0. −2 x ≥ −3. 2 x ≤ 3. x ≤ 3/2 = 1.5. Then the domain is "all x ≤ 3/2". The range requires a graph. WebExample 5. Find the domain and range of the following function. f (x) = 2/ (x + 1) Solution. Set the denominator equal to zero and solve for x. x + 1 = 0. = -1. Since the function is undefined when x = -1, the domain is all real numbers except -1. Similarly, the range is all real numbers except 0. inappropriate shows for teens https://bneuh.net

Web2 Answers. Sorted by: 1. To find the range of the function put x + 1/x =y This will reduce to x^2 +1 -yx=0. Now since x is real therefore the discriminant of the above equation should be Non Negative which gives y^2 - 4 >=0 which gives y>=2 and y<=-2. Hence the range which is y is y>=2 and y<=-2. Share. WebIf we use interval notation, we can write Range (f) = [-1, +\infty) Range(f) = [−1,+∞) . In this example, we could have solved it using the fact that f (x) = x^2 - 4x + 3 f (x) = x2 −4x+3 is a quadratic function, and its graph is a … WebJul 18, 2024 · Example 4.7.1. Find the domain and range of the following function: f(x) = 5x + 3. Solution. Any real number, negative, positive or zero can be replaced with x in the given function. Therefore, the domain of the function f(x) = 5x + 3 is all real numbers, or as written in interval notation, is: D: ( − ∞, ∞). Because the function f(x) = 5x ... inappropriate shows on disney+
