Question

At x = 3, the function given by f(x)={x2 ,6x−9,x<3x≧3 is

Answer 1

Applying the definition, it is found that at $x = 3$, the value of the function is 9.

The definition of the piece-wise function is:

$f(x) = x^2, x < 3$

$f(x) = 6x - 9, x \geq 3$

At x = 3, it enters the second definition, thus:

$f(3) = 6(3) - 9 = 18 - 9 = 9$

Thus, the value of the function is 9.
