The equation of a curve is described by the function y=f(x)= \/x^2-4

which inequality gives the DOMAIN of the function?

a) x > 2

b) x < -2

c) -2 < x < 2

d) x < -2 or x > 2

answer:

step-by-step explanation:

answer: it's d

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
