X=first train speed
y=second train speed
sum of speeds is 725.2
x+y=725.2
x is 10.8 more than y
x=10.8+y
subsitute 10.8+y for x
10.8+y+y=725.2
10.8+2y=725.2
minus 10.8 from both sides
2y=714.4
divide both sides by 2
y=357.2
x=10.8+y
x=10.8+375.2
x=386
the speed of first train is 386mph
second train is 357.2mph
Functions are used to represent graphs, and vice versa.
The function represented by the graph is 
The graph (see attachment) is an absolute value graph.
An absolute value graph is represented as:

Where

The vertex is the minimum or the maximum point on the graph.
So, we have:

The function becomes

The function also passes through the point (-1,0).
So, we have:


Remove the absolute bracket

Subtract 3 from both sides

Divide both sides by 3

Substitute -1 for (a) in 

Hence, the function represented by the graph is
