Question

Tanya saves $25 each week until she has enough to buy a coat she's been eyeing

Answer 1

The domain and the range of a function are the possible input and output values, the function can take.

The domain and range of Tanya's savings is [0,10) and [0,245], respectively.

Let:

$x \to weeks$

$y \to amount$

So, the equation is:

$y = 25x$

The domain is the number of weeks she used to save.

When $y = 245$ (i.e. the total savings), we have:

$245 = 25x$

Solve for x

$x = 245/25$

$x = 9.8$

Approximate

$x = 10$

Hence, the domain of the function is: [0, 10)

The range is the minimum and maximum amount she can save.

Before she starts to save, she has $0.

At the end of the 10th week, she has $245.

Hence, the range of the function is [0,245]
