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.
