Question 884127
x^2 is NEVER negative. Squaring a positive number leads to a positive number. Squaring a negative number gives you a positive result (eg: x = -3 ---> x^2 = (-3)^2 = 9)


So that means (x-2)^2 is NEVER negative based on the same reasoning as above.


Multiplying some number that's either 0 or positive by 7, which is positive, means the expression 7(x-2)^2 results in a number that's 0 or some positive number.


7(x-2)^2 is NEVER negative.


Therefore, <font color="red">c) -3</font> is NOT a possible output of the function. It's impossible to generate a negative number.
