Answer:
a) g(x) = f(x) + 3
So g(x) is a vertical translation of f(x), 3 units upwards
b) g(x) = 3x² - 1 + 3
g(x) = 3x² + 2
The graph has shifted 3 units upwards, so has the vertex.
The vertex of f is (0,-1)
Whereas the vertex of g is (0,2)
-1 + 3 = 2
Answer:
B. The charge per kilowatt-hour.
Step-by-step explanation:
We have been given that an electric company charges a certain rate per kilowatt-hour of electricity used and an administrative fee of $3.50. The company charged Zhao $63.25 for using 800 kWh of electricity.
The equation represents the total amount of bill charged by electricity comapany to Zhao for 800 kilowatts of electricity use.
Since total bill is $63.25, administrative fee is $3.50 and total use of electricity is 800 kilowatts, therefore, r represents the charge per kilowatt hour and option B is the correct choice.
