Complete the function table below for the function f(x) = x2 + 1.
x1234
f(x)2
the numbers in the second row of the completed table make an arithmetic sequence.
a. true
b. false

The answer is true, and let me explain this to you like this:
F(x) = 4x - 6
when x = 1, F(x) = 4 * 1 - 6 = -2
when x = 2, F(x) = 4 * 2 - 6 = 2
when x = 3, F(x) = 4 * 3 - 6 = 6
when x = 4, F(x) = 4 * 4 - 6 = 10
second row is: -2, 2, 6, 10
differences are: 2 - (-2) = 4; 6 - 2 = 4; 10 - 6 = 4
So, the second row is in arithmetic progression.
Hope this is what you were looking for
