Given $$f(t)$$ and $$g(t)$$ as shown below GATE EE 2011 Engineering Mathematics - Transform Theory Question 10 English

$$g(t)$$ can be expressed as

$$g(t)=f(2t-3)$$

$$g\left( t \right) = f\left( {{t \over 2} - 3} \right)$$

$$g\left( t \right) = f\left( {2t - {3 \over 2}} \right)$$

$$g\left( t \right) = f\left( {{t \over 2} - {3 \over 2}} \right)$$
