The quadratic function f(x)=x^2 has how many zeros

sp2606 [1]

Given:

The quadratic function is

$f(x)=x^2$

To find:

The number of zeros.

Solution:

We know that,

Number of zeros of a polynomial = Degree of the polynomial.

We have, a quadratic function is

$f(x)=x^2$

Here, degree of function is 2.

For zeros $f(x)=0$ .

$x^2=0$

$x=0$

Therefore, the number of zeros of given quadratic function is 2 which are 0 and 0.
