Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

where a, b, and c are numerical constants and c is not equal to zero. Note that if c were zero, the function would be linear. An advantage of this notation is that it can easily be generalized by ...

# Write a Python function, evalQuadratic(a, b, c, x), that returns the value of the quadratic a⋅x2+b⋅x+c. # This function takes in four numbers and returns a single number. def evalQuadratic(a, b, c, ...
