Answer

is a range value AND a domain value.

Question 8

The total distance for traveling to Houston Raceway can be found by using the function $$y=2.25x+20$$ , where x is the number of miles driven. If most racers drive between 18 and 32 miles, find the domain and range of the situation and determine whether this function is continuous or discrete.

Accepted Answer

Continuous
$$D:\ 18\le x\le32$$
$$R:\ 60.5\le y\le92$$

Answer

Continuous
$$D:\ 60.5\le y\le92$$
$$R:\ 18\le y\le32$$

Answer

Discrete
D: {18, 18.5, 18,5,...32}
R: {60.5, 61, 61.5,...92}

Answer

Discrete
D: {60.5, 61, 61.6,...92
R: {18, 18.5, 18,5,...32}
