Points of Inflection
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
Sample: the first question, solved
Find the potential point of inflection for f(x)=x³−6x²+9x, setting f''(x)=0.
📘 Worked solution
✓f'(x)=3x²−12x+9, f''(x)=6x−12=0, so x = 2.
And one from the hard end
"For f(x)=x⁴−4x³+2, find all potential points of inflection, verify each, and explain what this reveals about the curve's shape."
