Determine whether each relation is a function if so provide the domain and range

Answers:

Explanation:

x = width

y = area

x is the input while y is the output.

We have a function because each input leads to exactly one output only. We don't have repeated x values.

The domain is the set of possible inputs. So we simply list the set of x values given in the table to get the domain to be {1,5,10,11,14}

The range is a similar story, but we list the possible y outputs getting {6,50,150,176,256}.

The curly braces indicate we have a set of values.

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

your answer is  

a.
