Question

Question 21 (1 point) This table shows the 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? x −3 −2 −1 0 1 2 3 f(x) −1.5 −1 −0.5 0 0.5 1 1.5 Enter your answer in the box. (Enter the number and nothing else)

Answer 1

Answer:

2

Step-by-step explanation:

x     f(x)      

−3    −1.5

−2    −1

−1     −0.5

0     0

1      0.5

2     1

3     1.5

This table shows the input and output values for a linear function f(x).

Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.

Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
