It should be -101. Just plug in 9 into x so it would be like f(9)= 9^2-20. Which equals -101

Answer:

-101

Step-by-step explanation:

Put 9 where x is, and do the arithmetic.

f(x) = -x² -20

f(9) = -9² -20 = -81 -20

f(9) = -101

No, John is incorrect.

<h3>Correct work shown:</h3>

$\sf x^2 - 6x - 7 = 0$

$\sf x^2 - 6x = 7$

$\sf x^2 - 6x + 9= 7 + 9$

$\sf (x-3)^2= 16$

$\sf x-3=\pm \sqrt{16}$

$\sf x-3= \pm 4$

$\sf x= + 4 + 3 \quad or \quad x = -4 + 3$

$\sf x= 7 \quad or \quad x = -1$

The correct answer should be x = 7 or x = -1
