Question

Which expression represents the composition [f.g](x) for the functions below?
f(x) = 2x + 3
g(x) = x-6
2x-9
O 2x - 3
2x - 15
O 2x2 - 9x - 18

Answer 1

The answer is 2x-9
Explanation:
[f.g](x) = 2(x-6) + 3
2 times x = 2x
2 times -6 = -12
The positive 3 remains how it is
The equation after distributing is : 2x-12+3 simplify the -12 +3 = -9
Your final equation will be 2x-9
