Question Image

To find: number of real zeroes
Let us find the points at which curve touches

x

axis.
A parabola is the graph of a quadratic polynomial in one variable.
The number of zeros is the points where the parabola touches the x axis.
The zeroes of each curves are given as (a) two (b) one (c) zero
So, the number of real zeroes is (a) two, (b) one and (c) zero
Hence, Option 4 is correct
