Ascience 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? a. the line will shift vertically up by 125°. b. the line will shift vertically up by 25°. c. the line will shift vertically down by 125°. d. the line will shift vertically down by 25°.
