This graph is that of a parabola, which in turn represents a quadratic (2nd order) equation, also a polynomial. The domain of any and all polynomial(s) is "the set of all real numbers," or (-infinity, infinity).
Answer: The answer is y=-3x
Step-by-step explanation: You can see in the picture that the line is going down which represents a negative slope so you can eliminate C and D. Now you are left with A and B. 1 unit up is equal to 3 so the rise over run is -3/1 and that translates to Y=-3x answer B
Irrational would be the correct answer
Answer:
64
Step-by-step explanation:
can be found by first finding 
then taking that result and putting it into the function 
.
means we are going to take the expression 
and evaluate it for 
:
So 
.
So we have this so far:
.
was found by replacing 
in 
with .
