Asked by me;

the function t= 19m + 65 represents the temp (t) of an oven preheating for minutes (m)
A: identify the independent and dependent variables
B: a recipe calls for an oven temperature of 350. describe the domain and range of the function

A. Independent variable: m (minutes). Dependent variable: t (temperature in degrees).

B. Solve 350 = 19m + 65 → 19m = 285 → m = 15 minutes.
- If you consider only the preheating up to the required 350°F, domain: 0 ≤ m ≤ 15 (minutes) and range: 65 ≤ t ≤ 350 (degrees).
- (If the model is allowed to continue past 350) unrestricted domain: m ≥ 0 and range: t ≥ 65.
