Algebra 16 – Modulus graphs
You’ll learn
- Sketch the V-shaped graph of y = |ax + b| from the vertex plus a point each side
- Find the vertex by setting the contents of the modulus to zero
- Read f(x) = g(x) and f(x) > g(x) answers off the intersecting graphs
- Verify graph-read intersection points algebraically by squaring
