Question

This table shows a linear relationship with a constant difference of 1 between consecutive y-values as x increases by 1.
Linear Relationships:
x = -1, 0, 1, 2, 3
f (x) = -2, 2, 6, 10
Using function notation, what is the equation described in the table? (1 point)
f(x) = ___x + ___

Answer 1

f(x) = 4x + 2

(Slope = (2 - (-2)) / (0 - (-1)) = 4, and f(0) = 2 gives the y-intercept 2.)
