Answer:
C. f(x) = 40(1/4)^x
Step-by-step explanation:
Check all the options:
When x = 0
A. f(x) = 1/4(40)^x
f(x) = 1/4(40)^0
f(x) = 1/4(1)
f(x) = 1/4
When x = 0
B. f(x) = 1/2(40)^x
= 1/2(40)^0
= 1/2(1)
f(x) = 1/2
When x = 0
C. f(x) = 40(1/4)^x
= 40(1/4)^0
= 40(1)
= 40
When x = 0
D. f(x) = 4(1/3)^x
= 4(1/3)^0
= 4(1)
= 4
Step - by - step - explanation
So first find out the pattern. As you can see it just minuses 2 each time. So first
18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.
So 2 is the ninth of the pattern, so 2 will be your answer.
Hope this helps.
