Answer:
See proof below
Step-by-step explanation:
We will use properties of inequalities during the proof.
Let . then we have that . Hence, it makes sense to define the positive number delta as (the inequality guarantees that these numbers are positive).
Intuitively, delta is the shortest distance from y to the endpoints of the interval. Now, we claim that , and if we prove this, we are done. To prove it, let , then . First, then hence
On the other hand, then hence . Combining the inequalities, we have that , therefore as required.
It is definitely d ( i need 20 characters ignore this part)

Answer:
The most basic quadratic function is y = x2. This is also called the parent function of a quadratic function. Sometimes you will see it written in function notation as f(x) = x2. The graph of y = x2 looks like the graph below.
We can calculate the speed to be
.. (36 mi)(0.75 h) = 48 mi/h
or we can just assume that is what it is based on the fact that 48 is the only number in any of the offered answers.
distance = speed * time
.. y = 48 * x . . . . . . . . . . . . . . . . corresponds to selection A
_____
There is no question 17.
_____
15. All sections of the graph are linear. All sections except Q show the function increasing (left to right, which is how we talk about it). Thus selection B is the only sensible one.
