Answer:

The positive zero is x=2

Step-by-step explanation:

we know that

The x-intercepts or zeros of the polynomial are the values of x when the value of y is equal to zero

we have

[tex]y=4-x^{2}[/tex]

so

For y=0

[tex]0=4-x^{2}[/tex]

solve for x

[tex]x^2=4\\x=\pm2[/tex]

so

The zeros of the polynomial are x=-2 and x=2

therefore

The positive zero is x=2
