\frac{7}{9}\ cup\ of\ milk\ for\ x\drinks\\\\
making\ proportion:\\
\frac{1}{3}-1\\
\frac{7}{9}-x\\\\
cross\ multiplication\\\\
\frac{1}{3}x=\frac{7}{9}\ \ \ \ multiply\ by\ 3\\\\
x=\frac{7}{3}=2\frac{1}{3}\\\\

Answer:

(a) The data set is a function, since for each input value {3,4,6,11} there is a single output value {5,7,11,21}

(B) A function is a mathematical relationship that associates one or more inputs with a single output value. So that the data set is not a function, there should be - for one or more values of the input - more than one output.

for example, if for the input value {3} there were two outputs {5, -5} then, the data set would not be a function.

The frelation $y ^ 2 = x$ is not a function because:
