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?

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

\(\large\tt \color{black}{f(x) = 89x - 100°}\)

\(\large\tt \color{black}{y = 89x - 100}\)


function change if the metal is at 25°

\(\large\tt \color{black}{y = 89x - 25}\)

plot the two graphs

and u will observe the change
