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 & .

answer: 1 + 1 = 11

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
