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).
