Step-by-step explanation:
(g+f)(x) ie option B
-2+1 = -1
1-2 = -1
4-5 = - 1
The mode is the number that appears most frequent within a given sequence.
To start us off, let's make a list of the numbers and how many there are.
0 : 1
1 : 2
2 : 1
12 : 1
13 : 1
21 : 1
22 : 1
31 : 2.
Now let's see which number(s) appears the most.
1 and 31 appear the most, so 1 and 31 are our mode.
Your answer is :
C.) 1 & 31.
I hope this helps!
Answer:
1. Discrete-time signals are represented mathematically as sequences of numbers. A sequence of numbers x, in which the nth number in the sequence is denoted x[n],
1 is
formally written as
x = {x[n]}, −∞ <n< ∞, (2.1)
2. where n is an integer. In a practical setting, such sequences can often arise from periodic
sampling of an analog (i.e., continuous-time) signal xa(t). In that case, the numeric value
of the nth number in the sequence is equal to the value of the analog signal, xa(t), at
time nT : i.e.,
x[n] = xa(nT ), −∞ <n< ∞. (2.2)
