Question

A science experiment begins with a metal at -100° Celsius. The following function describes the temperature change per minute: f(x) = 89x - 100°. How will the graph of this function change if the metal is at 25° at the start of the experiment?

Answer 1

2125

Answer 2

Equation becomes 89x-75, initial curves is offset of +25 on X axis.

Answer 3

But if you decrease it by 25 wont it still give you -100 C
