The graph of an absolute value function opens up and has a vertex of (0, -3).

Mathematics

Answer:

The domain: all real numbers;

The range:  y\ge -3.

Step-by-step explanation:

The graph of the function y=|x| opens up and has a vertex at (0,0). If the graph of an absolute value function opens up and has a vertex of (0, -3), then the function has an expression

y=|x|-3 (see attached diagram).

The domain of the parent function y=|x| is the set of all real numbers, then the domain of the function y=|x|-3 is the set of all real numbers too.

The range of the parent function y=|x| is y\ge 0, then the range of the function y=|x|-3 is y\ge -3.

Change the mixed leading number into an improper fraction...a b/c=(ac+b)/c

3900=2400-8a+20a

1500=12a

a=125 adults

substitute for a

c=300-a

c=300-125

c=175 children
