Answer:
The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4
Step-by-step explanation:
Given
Solving (a): The vertex;
Assume the general form of a function is
The vertex is determined by
By comparison, we have:
Solve for h, we have:
So, the vertex is:
The domain; x is all real numbers
From the function;
This can be rewritten as:
This implies that:
Whatever the value of is, it will be subtracted from 4 to give y or f(x);
Hence:
y is less than 4
<em>Option B answers the question</em>
Answer:
The opposite sides are always parallel.
It forms an acute angle.
The obtuse angle is greater than 90 degrees but less than180 degrees. So if a bisector is introduced, the resulting angle is acute. An acute is less than 90 degrees.
Answer:
B
Step-by-step explanation:
Given the function
Find the average rate of change on interval
This value is negative only for so correct option is B
