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?

The line will shift vertically up by 125°.
The line will shift vertically up by 25°.
The line will shift vertically down by 125°.
The line will shift vertically down by 25°.

I think it is A, personally because you are going into the positives and not the negatives, get it?

anonymous · Answer

i don't really. kinda confusing me

i looked at it more and if it started at 25, then it would be
f(x) = 9x + 25, right

anonymous · Answer

and that is 125 more that the first one, so yeah it would be a
