Question
Can you please explain how to do this?
To solve an equation by finding x-intercepts, Cynthia graphed the function y=x^3-5x+|2x-3| Give several possibilities for the original equation.

Thank you  

Answer
To determine a factor, measure the distance in inches and call it x.

One effect on the factor is in the inches cubed.

Another effect on the fact is that it takes away 5 units for each inch it is away.

On top of that, 1.5 inches is a critical distance to be away.
The difference between x inches and 1.5 inches has a positive double effect on the factor.


Is this it what you're looking for?
