The temperature outside can be measured by listening to crickets chirp. If you count the number of chirps per minute, the temperature can be found using the formula T = 1/4C + 40. Define the domain and range of this function and describe reasonable values for each.
technically if we do not consider the real world scenario the domain and range both would be real numbers. But since we are constrained to the real world scenario there should be an upper and lower limits to C. Let's call it C_min and C_max so the domain is [C_min, C_max] now you'd be able to calculate the range yourself.
You could also get good estimates to C_min and C_max going backwards from taking T_min and T_max (because we can estimate T_min and T_max) but it's out of the scope of the question.
