Answer:
So the answer is A
Step-by-step explanation:
A)
[tex]f(x)=815.03(1.38)^{x}[/tex]
f(1) = 1124.74
f(2)= 1552.143
f(3) = 2141.9575
f(4)= 2955.901
f(5)= 4079.1439
So the answer is A
B)
[tex]f(x)=1.38x^{2} -2.64x+815.03[/tex]
f(1) = 813.77
wrong!
C)
[tex]f(x)= 1.38x+815.03[/tex]
f(1) = 816.14
D)
[tex]f(x)=815.03\sqrt{x} -1.38[/tex]
f(1)= 813.65
wrong!
