Question

Help? I give medals and fan :D

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?

AThe 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°.

@dancingdiamond ? are you still here?

Answer 3

Sorry! @DuckDynastyfan923 I'm here now. I don't understand what to even do! These kind of problems really confuse me

Answer 4

Well since you need to cancel out the -100 to get to positive, your answer will be higher than 100. Then, since you need it to be 25, you add 25 to 100. Do 25 plus 100.

Answer 5

Okay, so its 125. But does it shift up or down

Answer 6

Nevermind but thanks for the help!!

Answer 7

Up. :)
