First question
The given function is
g(x) = 1.8x^3 - 0.0034x + 0.5
To find x = 1, we would substitute x = 1 into g(x) = 1.8x^3 - 0.0034x + 0.5
We have
g(1) = 1.8(1)^3 - 0.0034(1) + 0.5
g(1) = 2.2966
To find x = 2, we would substitute x = 2 into g(x) = 1.8x^3 - 0.0034x + 0.5
We have
g(2) = 1.8(2)^3 - 0.0034(2) + 0.5 = 14.4 - 0.0068 + 0.5
g(2) = 14.8932
Thus, the correct option is the third one
