Answer: the answer is 35.1
Step-by-step explanation:
Number 6 the y intercept is 50 because that’s the point where it crosses the y axis and 7 I believe it would be D= 200
The domain is equal all real numbers

The degrees of the polynomial is odd (3x^7, 7 is odd), therefore the range is equal all real numbers
Answer: The point (0,0)
This point is also known as the origin
The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number
If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)
