It is not a function—an element from the domain is paired with more than one element from the range. Specifically, the input value of 4 corresponds to two output values: 5 and -4.
A function can only take on one output for each input. It only takes one input value to associate with more than one output value to be invalid as a function.

So you have to find the relationship between the pumpkin diameter (y) and the number of weeks passed (x) in a table, lets do it taking into account that the equation modeling such behaviour is:
y = 2x + 6, where x is the number of weeks and plus original 6 cm
x y
week diameter
0 6
1 8
3 12
5 16
10 26
substitute the x and y values in the equation to see how they fit into it
Answer:
6.9
Step-by-step explanation:
Since you are supposed to decrease the number in the ratio 3:8 or 3/8 you take the small number that is 3 to be the numerator and 8 to be the denominator then multiply it by 18.4.
That is 18.4×3:8= 184/10×3/8=6.9
So to decrease a number you multiply it with the smallest number as the numerator and the big number as the denominator
To increase a number you multiply it with the big number as the numerator and the small number to be the denominator

Answer:
y = 

Step-by-step explanation:
Use the points (9, 5) and (6, 1) to identify the slope of the graph
=
m = 
m = 
m = 
The y-intercept is -7 because -7 touches y axis causing it to be the y-intercept
