Marco is wrong. In order for an input-output table to be a function, there can only be one Y for every X, meaning that X cannot repeat as the same number twice.
Set 2 I think hope I get it right
1.4 times
because if next year is (1.4)^(x+1) and this year is 1.4^x by dividing them it wil be 1.4^1
Step-by-step explanation:
b is the anwser or 1005 so there u go
F(x) = x²
k = 2
f(x) + k = x² + 2
kf(x) = 2x²
f(x + k) = (x + 2)²
f(x + k) = (x + 2)(x + 2)
f(x + k) = x(x + 2) + 2(x + 2)
f(x + k) = x(x) + x(2) + 2(x) + 2(2)
f(x + k) = x² + 2x + 2x + 4
f(x + k) = x² + 4x + 4
f(kx) = (2x)²
f(kx) = 4x²
The answers are f(x) + k and f(x + k).
