Answer:
(d) f(x) = -x²
Step-by-step explanation:
For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...
f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)
f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)
Of the offered answer choices, the only one with a vertex at the origin is ...
f(x) = -x² . . . . . a=-1
Answer:
-16
Step-by-step explanation:
Given:
The sequence is defined as "triple v, then subtract 7 from the result".
To find:
The expression for the given sequence.
Solution:
Triple v means 3 times of v, i.e., 3v.
So, the result is 3v.
Then subtract 7 from the result. So, the expression for the sequence is

Therefore, the required expression is
.
Answer:
H
Step-by-step explanation:
Out of all of the answers provided, H seems like the equation that makes the most sense.

![[480 - (180)] = 300](https://tex.z-dn.net/?f=%5B480%20-%20%28180%29%5D%20%3D%20300)

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.
From that, H would be considered the best equation that Mr. Hanson would use.
Answer:
first graph: 1/3
second graph: 1
third graph: 1/2
Step-by-step explanation:
count how many blocks it moves up for rise and count how many blocks it moves to the right or left for run. Then just put it as Rise/Run.
