a) Period = (2π)/(π/2) =4
bi) 11.8 = -6.2 + c -> c = 18
bii) f(9) = 6.2 sin (3π/4) +18 = 3.1 sqrt(2) + 18
c) g(1.5) = a sin(π/2) + b = a + b =14.5
g(14) = a sin(13π/6) + b = a/2 + b =10.2
Solving simultaneously
a = 8.6 and b = 5.9
d) I don't understand the question. the greatest difference of function g(x) with what?

I did the simultaneously and my answers are slightly different. I’m not sure where I’ve gone wrong. yes! I don’t understand the last part either but thank you for your help!!!
Something's wrong with the question. Either the maximum and minimum points for f are wrong or the definition of f is wrong. See my explanation in screenshots.
