Best ResponseYou've already chosen the best response.2you have to substitute x=0, 1,2,3 then you have to compare the values f(x) and g(x) for each year. For example, if x=0, then we have: f(0) = 4*0 =0, and g(0)= 5*0+2=2, so f(0) < g(0) now, please do the same for other values of x

Best ResponseYou've already chosen the best response.2question: are f(x) and g(x) heights or rates?

Best ResponseYou've already chosen the best response.2if f(x) is a rate, then the corresponding height h, is given solving this differential equation: \[\Large \frac{{dh}}{{dx}} = 4x\]

Best ResponseYou've already chosen the best response.2I'm pondering...

Best ResponseYou've already chosen the best response.2my reasoning is: height h1 for f(x) is: \[\Large {h_1}\left( x \right) = 2{x^2}\] whereas height h2 for g(x) is: \[\Large {h_2}\left( x \right) = \frac{{5{x^2}}}{2} + 2x\] and we have h2>h1, if x>0, whereas h2=h1 if x=0

Best ResponseYou've already chosen the best response.0This doesn't really make sense, are the functions \[f(x)=4x~~and~~g(x) = 5x+2~~~~or~~~~f(x)=4^x~~~~and~~~g(x) = 5x+2\]

Best ResponseYou've already chosen the best response.0So it's exactly \[f(x) = 4x~~~~~g(x) = 5x+2\] like that right?

Best ResponseYou've already chosen the best response.0Ok so now we can put in values as Michele did above, to see so let x = 0 \[f(0) = 4^0 = 1\] \[g(0) = 5(0)+2=2\] So its not year 0

Best ResponseYou've already chosen the best response.0\[f(1) = 4^1=4\] \[g(1) = 5(1)+2=7\] year 1 \[f(2) = 4^2 = 16~~~~g(2) = 5(2)+2 = 12\]
