Question 949900

How do I find the points which intersects with the x-axis for the function: f(x)=-2|x+3|+7

Thank you
<pre>Set the piece-wise function equal to 0, which is the value of y on the x-axis. 
Then solve for x to find the ROOTS, or the zeroes of the function.
You should realize that the graph intersects the x-axis at the points, {{{highlight_green((matrix(1,3,-6&1/2,",",0)))}}} and {{{highlight_green((matrix(1,3,1/2,",",0)))}}}
