Solve for y if (2+y)/y = sqrt(2) and leave your answer in simplified surd form. 4. If g(x) = (4-x2)/x4, find the values of b if g(b) + g(1/2) = 60.

B.

Step 1: Start with the given equation.

$y^2 = x$

Step 2: Take the square root of both sides to solve for $y$.

$y = \pm \sqrt{x}$

Simplified answer: $y = \pm \sqrt{x}$

y = \pm \sqrt{x}

4.

Step 1: Given function.

$g(x) = x^2$

Step 2: Substitute $x = -1$.

$g(-1) = (-1)^2$

Step 3: Simplify the expression.

$g(-1) = 1$
