Given those four functions,
A. A(t)=$30000 (1+ 5.25/ 100) t
B. A(t)= $30000 (1+5.875/100)t
C. A(t)= $30000 (1+5.75/200)2t
D. A(t)=$30000 (1+5.5/400)4t
This is what the graph woulf look like.
The red line indicates the fuction A(t)=$30000 (1+ 5.25/ 100) t.
Blue represents A(t)= $30000 (1+5.875/100)t.
Green is A(t)= $30000 (1+5.75/200)2t.
And purple graph represents A(t)=$30000 (1+5.5/400)4t.
