keiko is planning to rent a hotel conference room for an event. the function graphed below shows the cost, $r(x)$ (in dollars), of renting the room for $x$ hours. find $r(5)$ and interpret this value. (a) $r(5)=square$ (b) the answer to part (a) means that renting the room for $square$ hours costs $$ square$.

keiko is planning to rent a hotel conference room for an event. the function graphed below shows the cost, $r(x)$ (in dollars), of renting the room for $x$ hours. find $r(5)$ and interpret this value. (a) $r(5)=square$ (b) the answer to part (a) means that renting the room for $square$ hours costs $$ square$.

Answer

Answer:

(a) To find $R(5)$, we look at the value of the function $y = R(x)$ when $x = 5$ on the graph. Suppose from the graph, when $x = 5$, $y=150$. So $R(5)=150$. (b) The answer to part (a) means that renting the room for 5 hours costs $150$ dollars.

Explanation:

Step1: Locate x - value on graph

Locate $x = 5$ on x - axis.

Step2: Find corresponding y - value

Find the y - value on the function curve at $x = 5$. Assume it is 150.

Step3: Interpret the result

The x - value is hours and y - value is cost. So 5 hours costs 150 dollars.
