IB Calculus Problem 7
The following figure shows part of the graph of the function \(f(x) = 2x^2\).
The figure is not to scale.
The line \(T\) is the tangent to the graph of \(f\) at \(x = 1\).
- Show that the equation of \(T\) is \(y = 4x - 2\).
- Find the x-intercept of \(T\).
- The shaded region \(R\) is bounded by the graph of \(f\), the line \(T\) and the x-axis.
- Write down an expression for the area of \(R\).
- Find the area of \(R\).
