Neither even nor odd
Step-by-step explanation:
The graph of y = -5x^2 - 2x + 6 is that of a parabola that opens down. This function is neither even nor odd because a point chosen at random is neither reflected in the y-axis nor reflected in the origin.
I think it would be the last one from my calculations im not positive but its what makes sense.
He is wrong because if a + b > c it doesn't follow that a^2 + b^2 > c^2
(a + b^2 will always be greater than c^2 but a^2 + b^2 will not always be.
.
An example:
Right angled triangle with sides 3, 4 and 5:-
3 + 4 > 5 but 3^2 + 4^2 = 5^2
