Given the piecewise function (2x - 4 if x < 4 18- xif x > 4 what is the value of f(3) + f(5)? I​

10000000000000000000000000000000

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
