Answer:
f(x) = 
Step-by-step explanation:
The given options are,
a) f(x) = 
b) f(x) = 
c) f(x) = 
d) f(x) = 
Now, among the given options only option (a) satisfies the criteria stated in the question i. e.,
1. f(x) → 0 as x → - ∞ and
2 f(0) = 1
so, the correct answer is,
f(x) = 
Y=x+4
x=0 y=4
x=1 y=5
x=2 y=6
x=3 y=7
plot the points at
(0,4) (1,5) (2,6) and (3,7)
Here’s your answer. Hope this helped!!
