Taking the torques acting about the fulcrum F we have, F11.8=Fx+F21.8
Substituting the values of F1,F2 and F, the distance 'x' is calculated
Or x=(501.8)(351.8)25
Or x=1.08 m or 1.1 m

Consider the surface given by the function f ( x , y ) = 4 x 2 + y 2 9 . What is the range of f? Determine any y-intercept(s) of f.
For range, I realize that x 2 + y 2 9 can be any number, so long as x 2 + y 2 9 is positive or equal to zero. However, when looking at f, we know that the denominator cannot equal zero, which means that x 2 + y 2 9 can be any number greater than 0. Would this mean that the range of f is ( 0 , )?
For the y-intercept, I know that both x and z need to equal zero. Would this mean that there are no y-intercepts because 0 is not in the range of f?
