Question

Please help me with this question 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 two values apart?Enter your answer in the box. xf(x)−3−1.5 −2−1−1−0.50010.52131.5

Answer 1

x = 0 and x = 2 are two inputs that are two values apart. The difference of outputs is calculated as follows:

$f(2)-f(0)=1-0=1$
