Question

Find f(-3) if f(x) = x 2

Answer 1

The value of given function for x = - 3 is 9

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
