Since   each    polynomial  is  expressed   in  terms   of  the square  of  an  expression, find    the square
root of each polynomial.

Now add the two binomial    square  roots.

4 . A


is  the cube    root    of  x.   is the square  of  

The cube    root    of  64  is  4;  4^2     =   16; 3   ×   16  =   48. So  f(64)   =   48.

5 . B
Every point on a circle is the same distance from the center. We can use the distance formula
to find the distance between (3,8) and (2,−1).


Only    a   point   that    has a   distance    of   from   (3, 8)  lies    on  the circle.

(4,17)  has a   distance    of   from   (3, 8).
