Answer 1

The parent function of f(x) is the absolute value function: g(x) = |x|.

From this function, the value of x was decreased by 3 units, so we have a horizontal translation of 3 units to the right.

`g^(\prime)(x)=g(x-3)=|x-3|`

Then, the value of the function was multiplied by the factor 1/2, which means a vertical shrunk by a factor of 2:

And finally, the value of the function increased by 1 unit, which means a vertical translation of 1 unit up:

`f(x)=g^(\prime)^(\prime)(x)+1=(1)/(2)|x-3|+1`

Therefore the correct option is the second one.
