Answer:
definition of cosine, definition of sine, pythagorean theorem, substitution, laws of exponents.
Step-by-step explanation:
Y=7 is linear
y=3x^2+1/2x-x^3+1 is neither
y=2x+5x^2-1 is quadratic
y=x/(x-1) is neither
y=(x^2+8x-20)/4 is quadratic
y=(x+5)(x-4) is quadratic
Step-by-step explanation:
they are the same because FIGH just the ENLARGEMENT of ABCD
Answer: 12
Step-by-step explanation:
when you “add” a negative number, always subtract that number!!

Step-by-step explanation:</h2>
This function represents greatest integer function, which is the most famous of the step functions, which is denoted by ![[x]](https://tex.z-dn.net/?f=%5Bx%5D)
. So, this function is defined as:
![f(x)=[x] \ the \ greatest \ integer \ less \ than \ or \ equal \ to \ x.](https://tex.z-dn.net/?f=f%28x%29%3D%5Bx%5D%20%5C%20the%20%5C%20greatest%20%5C%20integer%20%5C%20less%20%5C%20than%20%5C%20or%20%5C%20equal%20%5C%20to%20%5C%20x.)
. The graph of the greatest integer function has the following characteristics:
a) The domain of the function is the set of all real numbers.
b) The range of the function is the set of all integers.
c) The graph has a 
at 
and 
in the interval 
d) The graph is constant between each pair of consecutive integers.
e) The graph jumps vertically one unit at each integer value.
![f(x)=[x]-3](https://tex.z-dn.net/?f=f%28x%29%3D%5Bx%5D-3)
tells us that the original function has been shifted 3 units downward. So the correct option has been marked in the square red below.
