A correct graph is shown below.

Answer 2

Answer:

The correct statement is: Option: C

C. The slope of the first equation is not graphed the right way.

Step-by-step explanation:

The piecewise function is given by:

f(x)=   3x+1   if  x<2

and      4     if  2≤x<5

• This means that the graph of a function in the interval (-∞,2) is a line with a positive slope i.e. 3 and hence is a increasing line.

Also, there is a open circle at (2,7)

( since the inequality is strict i.e. x<2)

• Also, there is a horizontal line i.e. y=4 in the interval [2,5)

       i.e. there is a open circle at (5,4).

But the graph which is plotted for x<2

The slope of a line is: 1/3 and not 3

( Slope is defined as the ratio of change in y to the change in x)
