Question

@jhonyy9 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°.

Answer 1

@jhonyy9

Answer 2

I think maybe A?

Answer 3

so you know that f(x) = 89x -100 has a graph of a line
than for x = 0 will get y=-100

Answer 4

Okay

Answer 5

how you think for x=25 how many will get calculi the y = ?

Answer 6

4 times

Answer 7

no

f(x) = 89x -100

so for x=0 you get y=-100

yes ?

so at the start you know that the metal temperature is 25 degrees

Answer 8

yes

Answer 9

@jhonyy9 hello?

Answer 10

@jhonyy9
Is it A?

Answer 11

try graph it this case
