Who can solve this question?I will mark them as branlist.​

See below

Step-by-step explanation:

We have to show that is an unit vector.

To show this, we will find the modulus of and if its value is 1, it will be a unit vector.

So,

Thus, is a unit vector.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
