Determine the number of real solutions: 1. y = -x? +2 x + 6
2. y = 2x² - 6x + 5
3. y = x² + 8x + 16

Here is my answer.. correct me if im wrong.

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
