Chapter SH, Problem 1.18EP

To determine

To Graph : to analyze the graph

Explanation of Solution

Given information : a graph that shows time varies with units produced

Graph :

  

Interpretation : the graph of linear function is straight line and this graph is curved, so it is nonlinear.

The graph appears to cross $y$ axis at about 10, so $y$ intercept is 10, this means that it took 10 hours to produce first unit

The graph may cross $x$ axis as $x$ values increase part 100, but this can’t be determined from graph. However, after reading labels, it is understood that hours per unit can’t be negative, so graph should not cross $x$ axis

No mirror images can be detected, so there doesn’t appear to be any symmetry

The graph is continuously going down from left to right, so it is decreasing from $x=0$ to $x=100$ . This means that hours per unit is decreasing as number of units produced increases

There are no turning points in the graph, so number extrema can be identified. The graph appears to be approaching $x$ axis as $x$ values increase, so graph maybe approaching $0$ as $x$ increases
