uqqh .

anonymous · Answer

If you want a numerical answer it would be x>= 4

anonymous · Answer

i thouqht it was x<4

anonymous · Answer

OOPS you are correct  you need what is under the radical sign to be positive... I looked at it wrong.

anonymous · Answer

OOPS   x <= 4   it can be 4 because you CAN take the square root of 0

anonymous · Answer

Complete the inverse of F(x) below. If necessary, use the slash mark ( / ) for the division symbol. Do not include decimals or "F-1(y) =" in your answer.
F(x) = 3x - 2

F-1(y) = _________

anonymous · Answer

To find the inverse.. you switch the x's for the y's and the y's for the x's

F(x) can be thought of as Y
so
y = 3x - 2  is the original equation.
x = 3y - 2  I switched the x's and the y's
NOW SOLVE FOR Y
x = 3y - 2
x + 2 = 3y

x + 2
----- = y
   3

anonymous · Answer

so i would exactly write It like this

anonymous · Answer

F^-1(y) =    x + 2
                   -----
