Consider a signal x(t) as shown in the figure here. Plot the graph of x(-2t + 3) (where ‘t’ indicates continuous time domain)

Consider a signal x(t) as shown in the figure here. Plot the graph of x(-2t + 3) (where ‘t’ indicates continuous time domain) Correct Answer <img alt="F1 Uday.B 14-12-20 Savita D20" src="//storage.googleapis.com/tb-img/production/20/12/F1_Uday.B_14-12-20_Savita_D20.png" style="width: 232px; height: 191px;">

By applying the time shifting operation by 3 units, the graph becomes

x(t + 3)

Now, by applying the time scaling operation by 2, the graph becomes

x(2t + 3)

Now, by applying the time reversal operation, the graph becomes

x(-2t + 3)

A student has created a plot of y(t)=t2. He is need to show another graph of z(t)=t3 in the same plot. But every time he hits the plot() function- MATLAB generates a plot of z(t) vs t but on a different window. What is the error?
A big rectangular plot of area 4320 m2 is divided into 3 square-shaped smaller plots by fencing parallel to the smaller side of the plot. However some area of land was still left as a square could not be formed. So, 3 more square-shaped plots were formed by fencing parallel to the longer side of the original plot such that no area of the plot was left surplus. What are the dimensions of the original plot ?
