Answer:

None of the options is equivalent to the given function.

Explanation:

A. y = f(x)

y = 3x - 2

y^(2)=(3x-2)^(2)

= 9x^(2) -12x+4

So,
$y^(2) \\eq x^(2)$

Hence, the function given in A is not equivalent to the given function.

B. When x = 2, then

y = f(2) = 3(2) - 2

= 6 - 2

= 4

Hence, B is not equivalent to the given function.

C. y = 3x - 2

This means, the output value is 2 less than 3 times the input value.

Hence, C is not equivalent to the given function.
