MATLAB CODE ONLY!

Consider the following exponentially decaying continuous signal: f(t)=eat for a>0 Task 1 Plot f(t) [5%] (a) Write a code to plot f(t),5t5, for a=1 and a=2 in the same figure. Include this figure in your final report. (b) Discuss how f(t) changes with time what you may expect about the spectrum of f(t) when a increases
