Examples:
1. Using the equation f(x) = 3x - 1:
f(0) = 3(0) - 1 = -1
f(1) = 3(1) - 1 = 2
f(2) = 3(2) - 1 = 5
2. Using the equation f(x) = x^2 + 1:
f(0) = (0)^2 + 1= 1
f(1) = (1)^2 + 1 = 2
f(2) = (2)^2 + 1 = 5
3. Using the equation f(x) = x + 1:
f(0) = 0 + 1 = 1
f(1) = 1 + 1 = 2
f(2) = 2 + 1 = 3
Based on the given points, the correct equation that represents f(x) is "f of x equals x squared plus 1" or f(x) = x^2 + 1.
