The correct option will be the last one:
<em><u>Explanation</u></em>
The general equation for sinusoidal function is:
, where
Amplitude,
frequency and
y-intercept
Here the maximum value is 15 and the minimum value is -3. So, the distance between maximum and minimum values is 18. That means, the Amplitude, 
Frequency
is given as 3 and y-intercept
is 6
So, the required function will be:

Answer:
c=protons
Step-by-step explanation:
thats all i know sorry!
There no other figure but can take a property that is linear pair or linear pair axiom
Answer:
A.
Step-by-step explanation:
The trinomial
is of the form
. Then, it can be factored by searching two numbers that added are -12 and multiplied are 35. Those numbers are -7 and -5. Then,

So, the answer is A.
