Option C
Step-by-step explanation:
the point has to lie under or on the line (but not above
and under or on the parabola (but not above)
we can algebraicly check this if we put the x- and y-Informations into the given inequalities
A) 1 <= -4+3
1 <= -1
so a can't be true
B) 2 <= -2 + 3
2 <= 1
that's out of the race too
C) 0 <= -(-1)+3
0 <= 4
thats true. Let's check for the parabola
0 <= (-1)² - (-3)
0 <= 1 + 3
0 <= 4
That's also true and therefore the solution
Just for the lolz, let's check up on the last option
D) -1 <= -1+3
-1 <= 2
that's a true and valid statement
let's check for the parabola
-1 <= 1² -3*1
-1 <= -2
That's not true of course. so C is the only possible option.
(would really, reallly appreciate the brainliest, if you appreciate my work)
