Given that (6 3) is on the graph of f(x) find the corresponding point for the function f(-1/2x)
Vlada [557]
\bf \begin{array}{rllll}
(6&,&3)&f(x)\\
x&&y\\\\
(-\frac{1}{2}x&,&3)&f(-\frac{1}{2}x)\\\\

(-3&,&3)

There are 16 students playing kickball. Two students leave to go play hopscotch. How do you write the fraction of children left
olga55 [171]

Answer:

7/8
