We want to graph the following function:
[tex]f(x)=7|x+2|-3[/tex]
This is a modulus function(a line reflected on the y-axis) moved 2 to the left, and 3 down. The 7 represents the slope of this graph. The graph is like this:
To plot this in your software, you're going to need the lowest point and one point at the right side of the lowest point.
Its lowest point is (-2 , -3).
Let's calculate this function at x = -1.
[tex]f(-1)=7|-1+2|-3=4[/tex]
The other point could be (-1 ,4)
