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
That 1,2,3,4,5,6 is one the die and it has a chance to at least get all the numbers at least once but u dont have enough data so i can help u more.
To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.
<h3>What is
cause-effect relationship?</h3>
A cause-and-effect relationship is one which satisfies some conditions like:
- two events occur at the same time and in the same place
- one event immediately precedes the other
Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.
