Answer:
The withdrawal of $25 involved more money.
Step-by-step explanation:
We have been given that one customer made a $25 withdrawal from a savings account. The other customer made a $15 deposit.
We know that withdrawal stands for negative number, so withdrawal of $25 would be
The absolute value of would be
.
We know that deposit stands for positive number, so deposit of $15 would be .
The absolute value of would be
.
Since the absolute value of withdrawal is more than deposit, therefore, withdrawal involved more money.

The equation of the piecewise function is
On the graph, we have:
- y = 3 for all x values not more than -1
- y = -1 for all values greater than 2
Hence, the piecewise function is:
This is the set of input values
In (a), we have:
x ≤ -1 and x > 2
Hence, the domain is (∞, 3] u (2, ∞)
<h3>The range of the function</h3>This is the set of output values
In (a), we have:
f(x) = 3 and f(x) -1
Hence, the range is [3] u (-1)

Step-by-step explanation:
Since, roots are - 3 & 2
Therefore, (x + 3) & (x - 2) would be factors.
Leading coefficient is 5
Hence, required quadratic equation is:
