F(x) = x + 2 g(x) = 3x^2 – 5 Find (f. g)(x).

O A. (f. g)(x) = 3x^3 + 10
OB. (f. g)(x) = 3x^3+ 6x^2 = 5x+ 10
Oc. (f. g)(x) = 3x^3 +6x^2 – 5x - 10
OD. (f. g)(x) = 3x^3 - 10
what is the answer​

The average daily maximum temperature for laura’s hometown can be modeled by the function f(x)=4.5sin(πx/6)+11.8 , where f(x) is the temperature in °c and x is the month. x = 0 corresponds to january.what is the average daily maximum temperature in may? round to the nearest tenth of a degree if needed.use 3.14 for π .
