Question

In Problems 61-68, determine which of the equations specify functions with independent variable x. For those that do, find the domain. For those that do not, find a value of x to which there cor- responds more than one value of y. 61. $x^2 - y = 1$ 63. $x + y^2 = 10$ 65. $xy - 4y = 1$ 67. $x^2 + y^2 = 25$ 62. $x - y^2 = 1$ 64. $x^2 + y = 10$ 66. $xy + y - x = 5$ 68. $x^2 - y^2 = 16$

Step 1

√x This equation specifies a function with independent variable x. The domain of this function is all non-negative real numbers, since the square root of a negative number is not defined. Show more…
