Algebra. Find the Domain and Range f (x)=2x. f (x) = 2x f ( x) = 2 x. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: (−∞,∞) ( - ∞, ∞) Set -Builder Notation: {x|x ∈ R} { x | x ∈ ℝ }
https://socratic.org/questions/how-do-you-find-the-range-of-f-x-2x-if-2-2-0-1-2. The range is the set of y values Explanation: Simply plug in all of your domain (x) values into your equation and calculate each y value. Be sure to use parenthesis correctly. Example: 2(−2)2 =2 ⋅4 = 8.

Jun 26, 2018 · How do you graph the function f (x) = 2x? | Socratic. Algebra Graphs of Linear Equations and Functions Graphs in the Coordinate Plane. 1 Answer. Rhys. Jun 26, 2018. Shown below. Explanation: find two points on the graph, then join them up. When x = −1 ⇒ y = 2 ⋅ ( − 1) = −2. x = 1 ⇒ y = 2 ⋅ (1) = 2. Hence we get two point ( − 1, −2) and (1,2)

To evaluate a function is to: Replace ( substitute) any variable with its given number or expression. Like in this example: Example: evaluate the function f (x) = 2x+4 for x=5. Just replace the variable "x" with "5": f ( 5) = 2× 5 + 4 = 14. Answer: f (5) = 14. More Examples. Here is a function: f (x) = 1 − x + x 2. f is just a name,
