Question

T(p) is a function that models the average yearly temperature based on the degree latitude(p) of the location on earth. The lines of latitude run from East to West, but they are measured in terms of North and South, extending from −90° to +90°. Which domain is appropriate for this function?

Answer 1

Answer:

All the real numbers between $\pm 90^\circ$ including $\pm 90^\circ$.

Step-by-step explanation:

T(p) models the average yearly temperature based on degree latitude of the location.

Since the lines of latitude runs from East to West and extending from $-90^\circ$ to $+90^\circ$, they can be included in the domain.

Also, the degrees of latitude can be fractional units, positive units, or negative units. Therefore, the domain appropriate for this function is All the real numbers between $\pm 90^\circ$ including $\pm 90^\circ$.

Answer 2

Answer:

D = all real numbers between ± 90, inclusive

Step-by-step explanation:

Degrees of latitude can be fractional units, positive units, or negative units.
