Answer 2

To find the value of Y when x = 1/4 in the equation Y = 3/x - sqrt(x), we can substitute the value of x into the equation and perform the necessary calculations.

Plugging in x = 1/4, we have:

Y = 3/(1/4) - sqrt(1/4)

To simplify this expression, we need to remember that dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite 3/(1/4) as 3 * (4/1):

Y = 3 * (4/1) - sqrt(1/4) = 12 - sqrt(1/4)

The square root of 1/4 is 1/2, so we can further simplify the equation:

Y = 12 - 1/2 = 12 - 0.5 = 11.5

Therefore, when x = 1/4, the value of Y is 11.5.
