Question 111894
please help me solve this problem, i have been out of school for 28 years and have never did algebra. so iam thanking you in advance for your help. 
i have to find the output for the negative in the frist row and the out put for non-negative in the second. find the indicated function values. 
the problem 
<pre><font size = 5><b>
       [6x - 1 if x < 0
f(x) = [
       [7x + 3 if x <u>></u> 0

Here is the graph of this:

{{{drawing(400,750,-5,5,-10,10,
graph(400,750,-5,5,-10,10, (6x-1)*sqrt(-x)/sqrt(-x)),
graph(400,750,-5,5,-10,10,(7x+3)*sqrt(x)/sqrt(x)),
locate(-.1,-.78,O), locate(-.1,3.22,O), locate(-.1,3.22,o),
locate(-.1,3.22,":"),locate(-.1,3.22,"0"),locate(-.1,3.22,"+"),
locate(-.1,3.22,"*"),locate(-.1,3.22,"d"),locate(-.1,3.22,"P")   )}}}

The line below the x-axis is the graph of the output for
negative values of x, and the line above the x-axis is 
the graph of the output for the non-negative values of x.

Notice that there is an open circle at the right end of
the lower part of the graph [at (0,-1)] and a closed 
circle at the left end of the upper graph [at (0,3). These
indicate that the graph does not include the point (0,-1)
where the open circle is located, but does include the
closed circle (0,3) where the closed circle is located.
