Question 1
Sketch the graph of \( f(x) = 2x^2 - 3x + 1 \) and show both a secant line between \( x=0 \) and \( x=2 \) and a tangent line at \( x=1 \).
💡 Hint: Calculate points and slopes for both lines before drawing!
Question 2
For \( f(x) = x^3 - 2x + 1 \), determine the coordinates of the point on the curve where the tangent line has the same slope as the secant line from \( x=-1 \) to \( x=1 \).
💡 Hint: Start with the secant's slope first!
