PLZ HELP ME!! if F(x) = x - 7 and G(x) = x, what is G(FX))?

G(F(x)) = x-7

Step-by-step explanation:

G(F(x)) is composition of functions that means to plug in F(X) into G function.The new variable will be F(X) instead of  X.

G(x) = x, F(x) = x - 7

G(F(x)) = x-7

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
