The function g(x) = –3x2 – 36x – 60 written in vertex form is g(x) = –3(x + 6)2 + 48. Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = –3x2 – 36x – 60? The graph of f(x) = x2 is made narrower. The graph of f(x) = x2 is shifted right 6 units. The graph of f(x) = x2 is shifted down 48 units. The graph of f(x) = x2 is reflected over the y-axis.

Answers

The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.

Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.

From the choices we only have:
The graph of f(x) = x2 is made narrower

A. The graph of f(x) = x2 is made narrower.

The clearance sale advertised 1/3 off the list price of clothes and 1/2 off the list price of luggage. Ramon bought a suitcase with a list price of $100 and a coat with a list price of $195. What was his total bill?A. $115
B. $150
C. $180
D. $295

Answers

The closest answer C, however the actual answer is $196.25.

price of the coat = 2/3*195 = 2*195/3 = 2*65 = 130
price of the luggage = 1/2*100 = 100/2 = 50
total bill = 130+50 = 180

David recycles 5 cans every week. Which expression shows the total number of cans he recycles in w weeks?A.5w
B.w/5
C.5 + w
D.5 + 5w

Answers

the answer would be option A
because if you know that David recycles 5 cans a week every week that the week would turn into w and 5 would stay the same so when you put 5 and w (week) together you would get 5w
(i am not sure if that is right thought i am taking a test with the same question)

p.s. sorry if i confused you i don't really know how to explain it

a because 5 per week so 10 in two weeks etc...so 5 per (w) any number of weeks
hope i help
