Problem the diameter of a human hair is 9*10 ^-5 the diameter of a spider's silk is 3*10^-6 meters. how much greater is the diameter of a human hair than the diameter of a spider's silk? write your answer in scientific notation.

(- 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 )
