The function f (x) = x3 + 2x2 - 4x – 6 has a relative maximum and relative minimum located at which of the following x- valúes?

true

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

noncoplanar points are points that do not lie on the same line.
