It is given that $f(x)=-2x^2+10$

Consider the following three curves:

(1) $y=f(x)$

(2) $y=f(x+1)$

(3) the curve $y=f(x+1)$ reflected in the line $y=6$

The trapezium rule is used to estimate the area under each of these three curves between $x=0$ and $x=1$.

State whether the trapezium rule gives an overestimate or underestimate for each of these areas.
