Question

*****HELP PLEASE*****

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?

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°.

Answer 1

So you will be going from y = -100 to y = 25

-100 to 25 is up the Y-axis 125 units right?

Answer 2

This is because the outside constant is your vertical shift
