Step-by-step explanation:

Given

Required

Write as exponential function

An exponential function is represented as:

Apply law of indices

The above represents the exponential function

The amount saved in June is;

$(2x + 4)

Step-by-step explanation:

Here, we want to get the amount saved in June

From the question, she saved $5 more than twice here usual amount

twice here usual amount is 2 * x = $2x

So, adding the extra $4; the amount saved will be;

2x + 4
