What are the domain and range of the function f(x) = x4 - 2x2 - 4?
domain: all real numbers
range: all real numbers greater than or equal to -5
domain: all real numbers
range: all real numbers greater than or equal to -4
domain: all real numbers between -2.5 and 2.5
range: all real numbers
domain: all real numbers between -2.5 and 2.5
range: all real numbers greater than or equal to -5

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

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
