Answer:
vertex = (4, - 8 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 4)² - 8 ← is in vertex form
with (h, k ) = (4, - 8 ) ← coordinates of vertex
The exponential function will be written as:
<span> y = 12 (0.56)^(t/4)
y=12(0.56^(1/4))^t
but
</span>0.56^(1/4)=0.8651
thus plugging the value in y we get:
y=12(0.8651)^t
in two decimal places we get:
y=12(0.87)^t

000 is the total cost of the house that a buyer bought.
Prior to that, he paid 10% of the amount for down payment.
Now, we need to find the amount he will need to pay to paid off the house he
bought.
=> 10% = 10 / 100
=> 0.1
We already have the value of 10%, now multiply this to the total amount of the
house
=> 220 000 x 0.1
=> 22 000 – he paid this amount for down payment.
Now, let’s subtract his down payment from the total amount.
=> $220 000 – 22 000
=> $198 000
Thus, the home buyer will pay 198 000 to paid off the house he bought.
