Question

while sam was at work, his house lost electrical power. by the time the electrical power came back on, the temperature inside the house was 88°f. the air conditioner immediately started to cool the house. let f(x) represent the temperature, in degrees fahrenheit, of sam’s house x minutes after the air conditioner started to cool the house. part b: use function notation to represent the temperature of the house when the air conditioner started to cool the house. enter your answer in the space provided. enter only your answer. f(30)=76f

Explanation:

Step1: Understand function definition

The function \( f(x) \) gives the temperature \( x \) minutes after the AC starts. When the AC starts, \( x = 0 \) minutes.

Step2: Represent initial time

So, the temperature when the AC started (at \( x = 0 \)) is \( f(0) \), and the initial temperature was \( 88^\circ\text{F} \), so \( f(0)=88 \).

Answer:

\( f(0) = 88 \)
