Confused on one-to-one functions. just need 11-14 plz(: u

11. YES. Because each x-value is only used once (no duplicate x-coordinates)

12. range is the y-values.  the lowest it goes is -2 (with an open dot), then it goes to +2 (with an open dot).  then there is a separate line where y = 4.

(-2, 2) U [4, 4]

13. f(-1): when x = -1, y = ???  (do not count the open dot!)

1

14. f(3): when x = 3, y = ???  (do not count the open dot!)

4

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
