Input 1, 3, 4, 3 output 1, 9, 16, 27

is it a function

A. yes, each input has only one output
B. yes, each output has only one input
C. yes, each output is the square of the input
D. no, the input 3 has 2 outputs

what would the answer be?

no the input 3 has 2 outputs so it would be D

Step-by-step explanation:

its not a funtion becues theres not a padern

a funtion would be like this

input 1, 3, 5, 7, 9

output 3, 6, 9, 12

thats a funtion

(- 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 )
