Will give brainliest and plz no fake answers This table shows input and output values for a linear function f(x).

What is the positive difference of outputs for any two inputs that are FOUR values apart?

Enter your answer in the box.

x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5

If you observer the value of x=0 and x=1, you can conclude that every 1 value of x increased, the f(x) will be increased by 0.5. The graph function should be:

f(x)= x/2

A positive difference means that the value should be always positive. To find 3 the positive difference of f(x) with 3 values of x apart, let use x=0 and x=0+3= 3. The difference would be:

f(x+3) - f(x)

f(3)- f(0)=

1.5 - 0= 1.5

The answer would be: 1.5

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
