Answer:
Choice A
Step-by-step explanation:
Real time mapping of a function to a new function
is known as Fourier transforms. The new mapped function is defined for an
interval of (-∞, ∞).
<span>While the Laplace transform is the counterpart, in which a function
is mapped to a new function on complex plane. Functions defined for span t≥0
are used by Laplace transformation. </span>
Its is a function. mentally connect the dots. run your pencil across the paper parallel to the y-axis. if none of the points have touch the pencil it is a function. another way to check. look at the X value of all the coordinates. if they are all different its a function.
1. 5+4
2. 7+2
The answer is 9.
I hope I helped! :)
