Find n(a) and n(at ), and their orthogonal complements n(a) ⊥ and n(at ) ⊥ for a =   1 1 1 0 0 1 2 −1 2 1 0 1  .

(- 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 )

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

its 50 miles away from the starting point

16 is the absolute value
