Question

1. The graph of x2 + 1 = 0

(a) Intersects x-axis at two distinct points.
(b) Touches x-axis at a point.
(c) Neither touches intersects x-axis.
(d) Either touches or intersects x-axis. nor​

Answer 1

Neither touches nor intersects x-axis.

The graph of y= x²+1 will be an upward parabola.

The vertex of the parabola will be at (0, 1).

The parabola will never intersect or touch the x axis.

Hence the correct option is C while rest of the options are incorrect
