An exponential function decays at a rate of 20% and has an inltlal value of 13.
Which represents the function?
A y = -13(0.2)'
BY = 13(1.8)
cy= 13 (0.2)
D y = 13(0.8)

(- 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 )

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
