If we know the temperature in degrees Celsius, C, we can find the temperature in degrees Kelvin, K, using this equation: K = C + 273.15 1. Complete the table with temperatures in Kelvin or in Celsius

2. The equation K = C +273.15 represents a function. Write an equation to represent the inverse function tells us in this situation.

Eric has challenged himself to walk 24,000 steps in 4 days. if eric walks the same number of steps each day, which function represents the number of steps eric still needs to walk to reach his goal with respect to the number of days since he started his challenge? a. y = 8,000x − 24,000 b. y = -8,000x + 24,000 c. y = 6,000x − 24,000 d. y = -6,000x + 24,000

Abcd is reflected across the x- axis, then rotated 90 clockwise about the orgin, and finally reflected across the line y= x to form a’ b’ c’ .
