How to solve option B
Solution
Now, here, we have put x = 0 and get y = 3.
It is because we need to find out at which point where the graph cuts at y - axis.
Similarly, we need to find at which point graph cuts at x - axis.
So, we put y = 0 in I,
So, (0.275, 0) and (-1.77, 0)
The shape of graph is downward parabola as the coefficient of x2 < 0.
