Identify points for quadratic and linear function.  Construct the product.

The result looks consistent with a degree-3 polynomial.

(m x + k) ( a x^2 + b x + c) is degree 3.

Degree 3 factors into (x - x1) * ( irreducible quadratic) or into (x - z1) ( x - z3) ( x - z3).

The former is the case here.

We could get the equations of the linear and quadratic if we knew the x scale.  We can impose any x scale.

Exponential * linear ...

Dividing by small numbers:  stacks of thin f(x) blocks.

Sketch graphs of f(x) = (x - 3) and g(x) = (x+ 2).
