Answer:
A, C and E are true.
Step-by-step explanation:
The domain is a set of natural numbers.
The recursive formula is correct:
When x = 1, f(x) = 4 and f(x + 1) = f(2) = 3/2 f(x) = 3/2 * 4 = 6.
It is also true for the other points on the graph.
D is incorrect.
E is correct exponential growth with the formula 4(3/2)^(x-1).
Answer:
x+y/4 = 1/2
x-3y/3 = 2
move variables to one side:
multiply the first equation by 4 to get: x+y =2
and the second equation by 3 to get: x-3y =6
then subtract the equations to cancel out x:
x+y = 2
- x-3y = 6
then u get
y--3y = 2-6
4y = -4
y=-1
substitute to solve for x:
x-1 / 4 =1/2
x-1 = 2
x=3
check:
3+-1
2/4= 1/2
correct!!!
The value of track is given by:
V(x)=32500(0.92)^x
when x=2
V(2)=32500(0.92)^2=$27508
when x=3
V(3)=32500(0.92)^3=$25,307.36
Difference in values will be:
27508-25307.36
=$2,200.64
