Determine the zeros of the function
5) y=-x² + 2x + 1

Solution:

We have to find the zeros of the function

Find the zeros of function:

We have two zeros

Thus zeros of function are

zeros of the function y=  is &

Step-by-step explanation:

Here we have , y= in order to find zeros of this quadratic function we get:

⇒

⇒

⇒

⇒

⇒

⇒      

Since, we have two root one with positive & other with negative sign so :

⇒

Therefore, zeros of the function y=  is & .
