Answer: g(x) is shifted left 2 units, down 4 units, and reflected over the x-axis.
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- a is the vertical stretch
- -a is a reflection over the x-axis
- (h, k) is the vertex
- --> h is the horizontal shift (positive is RIGHT, negative is LEFT)
- --> k is the vertical shift (positive is UP, negative is DOWN)
f(x) = x²
g(x) = -(x + 2)² - 4
a = -1 reflected over the x-axis
h = -2 shifted left 2 units
k = -4 shifted 4 units down

Answer:
-4
Step-by-step explanation:
20 - 24 equals -4 (24 is negative because the temperature drops)
Answer:
2) 25%
Step-by-step explanation:
Simple interest means the interest at the end of each year will always be 8% of 2000 (assuming he doesnt pay some of it off), and will not be compounded with the existing interest.
To get a percentage, multiply by the percentage/100, in this case i.e. multiply by 0.08.
2000*0.08 = $160.
Therefore he has $160 of interest each year to pay.
Now we just need to work out how many lots of 160 go into 640, i.e. divide through.
640/160 = 4 - therefore he has had the loan for 4 years.
