I need help plz someone help me solved this problem I need help ASAP! I will mark you as brainiest!

 (a)

               (b) A = $1680.67

               (c) t = 9.99 years

               (d) A = $1689.85

Step-by-step explanation:

  where

a) Given: P = 900, r = 7% = 0.07, n = quarterly = 4

b) Given: P = 900, r = 7% = 0.07, n = quarterly = 4, t = 9

A = 1680.67

c) Given: A = 1800, P = 900, r = 7% = 0.07, n = quarterly = 4

d)

Given: P = 900, r = 7% = 0.07, t = 9

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
