The answer is:
C.
In order to find the correct option, we need to substitute/evaluate the given values of "x" into each function.
Substituting into the first equation, option A:
... and so.
We can see that the option A is not the correct option since the obtained values do not match with the given values.
Substituting into the second equation, option B:
... and so.
We can see that the values obtained from the function do not match with the given values, so the option B is not correct.
Substituting into the third equation, option C:
So, since all the obtained values match with the given values, we can conclude that the correct option is the option C.
Have a nice day!
Answer:
b. x² + 8x + 12 =
1. use the factoring X (see attachment)
2. 6 x 2 = 12; 6 + 2 = 12
3. (x + 6)(x + 2) = 0
4. x = -6, -2
c. x² + 13x + 12 =
1. 12 x 1 = 12; 12 + 1 = 13
2. (x + 12)(x + 1) = 0
3. x = -12, -1
c. x² + x - 12 =
1. 4 · (-3) = -12; 4 - 3 = 1
2. (x +4)(x - 3) = 0
3. x = -4, 3
f. x² + 15x + 36 =
1. 12 x 3 = 36; 12 + 3 = 15
2. (x + 12)(x + 3) = 0
3. x = -12, -3
hope this helps :)
