Question

Please help with function table, I do not know which is the right one, DOUBLE 12 POINT REWARD!

Answer 1

Any number to the 0 exponent is equal 1, except 0

x = 0, f(x) = 2(0.5)^0 = 2 x 1 = 2

Only the fist table has x = 0 and f(x) = 2

Plug in the rest, matching f(x) in the table 1

x = 1, f(x) = 2(0.5)^1 = 2 x 0.5 = 1

x = 2, f(x) = 2(0.5)^2 = 2 x 0.25 = 0.5

x = 3, f(x) = 2(0.5)^3 = 2 x 0.125 = 0.25

Answer is A. first table
