The temperature at a point (x,y,z) is given by T(x,y,z) = 200e(-x²-(y²)/4-(z²)/9), where T is measured in degrees Celsius and x, y, and z in meters. There are lots of places to make silly.

What is the temperature at the point (1,2,3)?
a) T(1,2,3) = 150 degrees Celsius
b) T(1,2,3) = 120 degrees Celsius
c) T(1,2,3) = 100 degrees Celsius
d) T(1,2,3) = 180 degrees Celsius
