Web1/x 1 = 1/x 2. Cross-multiply both sides of the equation to simplify the equation. x 2 = x 1. x 1 = x 2. We’ve just shown that x 1 = x 2 when f (x 1) = f (x 2 ), hence, the reciprocal function is a one to one function. … WebFeb 17, 2024 · For example, if x = 2 is substituted into the function and results in y=8, then that is the only range value that can be associated with x=2. Some relations that classify as functions map several x-values to the same y-value. If x = -2 is substituted into the same function and also results in y=8, that is acceptable.

Can a function assign multiple inputs to the same output?

WebAnswer: We consider y=f(x) a function when there is a unique y-value for all x in the domain. If f(1)=10 and f(1)=2 then that violates the criterion that there is a unique y-value for a specified x=1.

WebLinear Function. A linear function is a function whose graph is a line. Linear functions can be written in the slope-intercept form of a line. f(x) = mx + b. where b is the initial or starting value of the function (when input, x = 0 ), and m is the constant rate of change, or slope of the function. The y -intercept is at (0, b). WebAug 9, 2024 · By definition, no. A function maps every X value in the valid domain to only a single Y value.

WebThink of a parabola, such as y=x 2. One y value will always have a pair of x values that arrive to that y value (in this case, symmetrically about x=0). A parabolic equation is a function; specifically y is a function of x when y=x 2, but x is not a function of y, because you do not get a specific value of x with any given y value. 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.

A function having more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept.

WebOct 24, 2024 · Can 2 different functions have the same domain and range? Hence, every given domain value has one and only one range value as a result, but not necessarily vice versa. In other words, two different values of x can have the same y -value, but each y -value must be joined with a distinct x -value. WebApr 11, 2024 · Ankush and Babulal walk around circular track.
