Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ± = ± 2
The number is - 2 or 2
<u>Answer:</u>
No
<u>Step-by-step explanation:</u>
We are given the following equation of a function and a table for the corresponding values of this function:
We are to determine if the equation and the table represent the same function.
To check that, we will substitute the value of x in the equation to see if it gives the same values of y as in the table.
---> (-30, 60)
---> (-28, 82)
---> )-26, 104)
Since these paired values differ from the ones given in the table. Therefore, table and equation do not represent the same function.
