Question

CAN SOMEONE HELP ME WITH TWO QUESTIONS PLEASE ? FANNING AND GIVING MEDAL !

Answer 1

For the first one, you have to look at which values under f(x) are negative, which are -16 and -8. Then look at the x values these correspond to, -8 and -6. The interval are for the x values, so you can rule out a and b since -2 and 0 correspond to positive values of f(x)

Answer 2

@snowflakepixie i was thinking it was C)

Answer 3

Well, -4 corresponds to 0, but this function is a parabola so if you plugged in something like -5, that f(x) value would be ngative

Answer 4

@snowflakepixie so which one would be the correct answer ?

Answer 5

D because it includes everything up to 0.

Answer 6

0 isn't really negative but it's not positive either
