Answer:

<u>-n - 5</u>

f^-1(x) = 5 or (-n - 5)/5

Step-by-step explanation:

g(n) = -5n - 5

RS | SR

Replace: y = -5n - 5

Switch n & y: n = -5n - 5

Solve for y:

n = -5y - 5. Isolate y

+5 +5

-1(n + 5) = (-5y) -1 Multiply each side by

-1 so that y isn't

negative.

<u>-n - 5</u> = <u>5y</u> Divide 5 on each side. 5

5 5 comes from 5y

<u>-n - 5</u>

y = 5

Replace y with f^-1(x):

<u>-n</u><u> </u><u>-</u><u> </u><u>5</u>

f^-1(x) = 5

Name two solutions to y = 3x - 5
wlad13 [49]

Answer:

(1,-2) and (0,-5) (There are an infinite amount more)

Step-by-step explanation:

The easiest way to find solutions is to plug in an x value. Let's try 1:

y = 3(1) - 5⇒y = 3 - 5⇒y = -2

(1,-2)

Let's try 0:

y = 3(0) - 5⇒y = 0 - 5 ⇒y = -5

(0,-5)
