Answer:

-2x - 3

Explanation:

f(x) = -1/2(x + 3) is the same as y = -1/2(x + 3)

change all y terms to x terms and all x terms to y terms

So change y = -1/2(x + 3) to x = -1/2(y + 3)

Now use the new equation and slove for y

x = -1/2(y + 3)

-2x = -2· -1/2 (y + 3)

-2x = y + 3

-2x - 3 = y

Rewrite your answer y = -2x - 3

Write the equation in the inverse
