Let the balance = Y and the number of weeks = x
She takes out 15 per week, so multiply 15 by x ( the number of weeks) to get 15x.
You would then want to subtract that from the amount she started with in her account.
The equation becomes: Y = 150 - 15x
Answer:
<u>Easy way to distinguish:</u>
- Linear function forms a AP and exponential function forms a GP
<u>We see f(x) is series of:</u>
- This is a AP with common difference of 6 and the first term of 8
<u>g(x) is series of:</u>
- 4, 12, 36, 108, 324
- This is a GP with common ratio of 3 and the first term of 4
1. <u>g(x) is exponential function:</u>
2. <u>f(x) is linear function:</u>
