## Question 6.2 (3 marks)

The diagram below shows the parabola $f(x) = -x^{2} + 2x + 8$ and a straight line $g$. The line $g$ cuts the parabola at point A on the left, which lies on the x-axis, and at point C(2;8) on the right. Prove that the straight line $g$ has the equation $g(x)=2x+4$.

Figure: Graph of a parabola f that opens downwards and a straight line g that slopes upwards. The line cuts the parabola at point A on the x-axis, left of the y-axis, and at C(2; 8) on the right.
