X
X + 2
X + 4
3x + 6 = 258
3x + 6 - 6 = 258 - 6
3x = 252
X = 84
84 + 2 = 86
84 + 4 = 88
Answer:
-g(x), g(2x), g(-x)
Step-by-st-ep explanation:
if f (–x) = f (x), so all of the signs are the same
you can also try on desmos, the graph is more helpful than words explain sometimes

Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
