Question

The graph of x²+1=0
a) Intersects x-axis at two distinct points.
b) Touches x-axis at a point.
c) Neither touches nor intersects x-axis.
d) Either touches or intersects x-axis.​

Answer 1

Step-by-step explanation

neither touches nor intersects x axis

x^2+1=0

x^2+0x+1=0

here,

b^2-4ac<0

Answer 2

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.
