[(-1,2), (0, 2), (5,2)) is a function.
true
false

I believe it is true.

Step-by-step explanation:

In order for it not to be a function, I think the x has to duplicate somewhere.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
