The next value should be 5 when \(x=3\)
When \(x=5\), \(y=21\)
Would you describe the pattern as linear, exponential or quadratic?
Explain your thinking. How might you convince your partner or a classmate?
It is quadratic as it does not grow additively or multiplicatively, rather it is a curve that has a minimum point at (0,-4) . It is symmetric as well with the line of symmetry through the vertex, (0,-4).
