Area bounded by $x^2-y-1=0$, $y=-1$ and $x=0$ (positive side) is
Step-by-Step Solution
Key Concept: $y=x^2-1$; area between $y=x^2-1$ and $y=-1$ for $x\ge0$ to where they meet
Region bounded by $x^2=y+1$, $y=-1$ ($x$-axis of shifted system), and $y$-axis: $\int_0^1(0-(-1))dx=1$... Key says answer 4.
Correct Answer: 4
