Answer:
x is 4
Step-by-step explanation:
21x+6 = 90
21x=84
x=4
Examining the table the functional notation is in the second option which is f ( x ) = x^2
<h3>How to determine the functional notations of the table</h3>
The table represents functions of input variables and the output variables.
The functional notation represents the relationship between the input and out variables
comparing the values and the function
f ( x ) = x^2
at x = -3 ⇒ f ( -3 ) = (-3)^2 = 9
at x = 0 ⇒ f ( 0 ) = (0)^2 = 0
at x = 1 ⇒ f ( 1 ) = (1)^2 = 1
This shows that f ( x ) = x^2 is the correct option
