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?


1) The line will shift vertically up by 125°.

2) The line will shift vertically up by 25°.

3) The line will shift vertically down by 125°.

4) The line will shift vertically down by 25°.

Answer 4

Instead of f(x) = 89x - 100
It will be
f(x) = 89x + 25

And that is equivalent of shifting the line vertically up by 125 (we move from -100 to 125)
