Determining the range of a function
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. WebFinal answer. Step 1/2. Determine the domain and range of the relation and determine whether the relation is a function. Relation is { ( 3, 2), ( 1, 7), ( 8, 10), ( 4, 4) } Domain of a relation is the set of all first elements of the ordered pairs of relation.

WebFor each number that you want to know whether or not it is in the domain, you plug in that number for x, and see if the answer makes sense. If I plug in 0, I get 0+5/0-3, which turns into -5/3. That's a real number, so 0 is in the domain of the function. If I plug in 3, I get 3+5/3-3, which turns into 8/0. WebOct 6, 2024 · Of course, we can also determine the domain and range of the square root function by projecting all points on the graph onto the x- and y-axes, as shown in Figures 3(a) and (b), respectively.
