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? (1 point)

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°.

Mercury · Answer

notice how the original equation is f(x) = 89x − 100° at the start of the experiment (when x = 0), f(x) = -100°, which is also the starting temperature of the metal now, if we want to change the starting temperature to 25, we would have to add 125°. how does this affect the graph? if you're still confused, please review vertical shifts on a graph https://courses.lumenlearning.com/ivytech-collegealgebra/chapter/graph-functions-using-vertical-and-horizontal-shifts/
