A: yes, f and g are both concave down

B: yes, f and g are both concave up

C: no, f is concave up and g is concave down

D : no, f is concave down and g is concave up

Step-by-step explanation:

if x = 1, then the answer is 3.5

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
