Question 949900: How do I find the points which intersects with the x-axis for the function: f(x)=-2|x+3|+7

You can put this solution on YOUR website! Whenever the value of x=0 the graph will intersect the x axis, and the value of x MUST be zero for the graph to intersect the x axis, so solve the function for x=0.

Thank you
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, and
