The vertex of a parabola is its highest or lowest point. Here, it is the lowest point, which happens right at the bottom of the U-shape—at (1, –4). Therefore, the answer is C.
If you subtract x from each side, it says Y = -x .
That tells you that the slope of the graph is -1, and the y-intercept is zero.
The graph is a straight line, passing through the origin.
It slopes DOWN from left to right, at an angle of 45 degrees.

Answer: The answer is (b) Neither I nor II.
Step-by-step explanation: We are given two equations and we need to find which is true. Since it is a simple algebraic question, so we just need to follow BODMAS rule to check the equations.
The equations are as follows -


Since L.H.S ≠ R.H.S, so this equation is not correct.


Since L.H.S ≠ R.H.S, so this equation is also not correct.
Thus, the correct option is (b) Neither I nor II.
