 Question 386971: Hi, Can someone please help me with this. Thanks y = + square root (2x-3) Explain the why this is a function State the domain and range Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!y = + square root (2x-3) Explain the why this is a function State the domain and range ------------------------- That "plus" sign in front of the square root says you are only going to have one y-value for each value of sqrt(2x-3). That makes it a function. ------ Domain: 2x-3 must be non-negative. Solve 2x-3>=0 x >= 3/2 Domain: All Real Numbers >= 3/2 ----- Range: Since y is never negative, Range: All Real Numbers >= 0 ========== Cheers, Stan H.
