Answer:
C and $320.45
Step-by-step explanation:
I think it's C because this is the full function :
And to get the b part of the question i just put the number in
I'm not a 100% sure, sorry if it's wrong
Answer:
im not sure what the answer is but good luck
Answer:
(f+g)(x)=f(x)+g(x)
=(-3x-5)+(4x-2)
= -3x-5+4x-2. collect like term
= -3x+4x-5-2
= x-7. the final answer

Any polynomial function has the domain of all real numbers. So here we'll choose a polynomial function in order to illustrate this problem. So any polynomial of the form:
meets our requirements. Therefore, if we set:
Then, we'll have:
- A domain of all real numbers and the range all real numbers that are greater than or equal to zero.
This is shown graphically in the figure below.
So for graphs, to tell if its a function is to see how many points are on the x-line for the coordinate. Functions will only have one point on each x-line.
With the top left, x = 0 has 2 points on it, so that is incorrect.
With top right, x = -1 has 2 points on it, so its incorrect as well.
Bottom left has 3 points on x = 0, so that's incorrect.
Bottom right, however, has no x-line where there are two or more points on it, so it is a function.
