Question

Write a function rule for the table

Answer 1

f(x) = x + 1

Explanation:

f(x) increase by 1 for every 1 increase in x. This is a linear function with a slope(m) of +1.

y = mx + b

y = x + b

The y intercept (b) is 1 (thevalue of y when x=0)

y = x + 1

This works for all the values listed.

f(x) = x + 1
