FNGR 1 | Lesson 3 | Solutions 2

Solutions:

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).
