Answer:
The value of given function for x = - 3 is 9
Step-by-step explanation:
Given as :
The y is the function of x is as
f( x ) = x²
So, For any value of x , the value of f( x ) should change
If, x = - 3
So, f ( - 3 ) = ( - 3 )²
Or, f ( - 3 ) = ( - 3 ) × ( - 3 )
i.e f ( - 3 ) = ( - × - ) ( 3 × 3 )
Or, f ( - 3 ) = ( + ) ( 9 )
∴ f ( - 3 ) = 9
So, The value of function f ( - 3 ) = 9
Hence , The value of given function for x = - 3 is 9 Answer

Answer:
(1, -1/2)
Step-by-step explanation:
7x - 2y = 8
5x + 2y = 4
I would use elimination to get rid of y
Add the two equations together
7x - 2y = 8
5x + 2y = 4
-------------------------
12x = 12
Divide each side by 12
x =1
Now find y
5x+2y = 4
5*1 +2y =4
Subtract 5 from each side
5+2y -5 = 4-5
2y = -1
Divide by 2
2y/2 =-1/2
y = -1/2
