: The of hours since 6 PM. outside, overnight temperature F (in degrees Fahrenheit) can be modeled by the function F(-0.3-5.41+71.8, for Osts 18, where is the number a. Compose the function y= R(R). Interpret the meaning of this function and determine its domain and range. b. Evaluate A(R6)) and interpret its meaning. c. Solve R(F) = 60 for t and interpret its meaning. d. Determine the relative minimum of A(F(0). What does this point represent in the context of the problem situation? Solve R(F(6)). Round to the nearest tenth if necessary.
