SAVINGS Natalie has $250 in her savings accountinto which she deposits $10 of her allowance each week. The balance of her savings account can be modeled by the function f(w) = 250 + 10w , where w represents the number of weeks. Write a function g(w) to represent the balance of Natalie's savings account if she withdraws $40 to purchase a new pair of shoes. Describe the translation of f(w) that results in g(w) .

Step-by-step explanation:

Given

Required

Determine g(w)

First, we'll write an expression for g(w)

From the question, we understand that she withdrew $40 from her account balance in w weeks.

This implies that:

Where f(w) is the account balance in w weeks and $40 is the withdrawn amount

Substitute 250 + 10w for f(w)

Recall that:

This means that function f(w) when shifter by 40 units downward, gives g(w)

it is x=-4
