Answer:
f(x) = -2x² + 2
Step-by-step explanation:
If you remember the y = x² parent graph, you will be able to derive your equation from visualization.
The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.
(-5,-3)! the third quadrant is the lower left of the coordinate plane. hope that helps!
Answer:
One rule for dividing fractions is the rule where instead of doing 13/43, you can do 13 times 1/43.
Step-by-step explanation:
Yeah
X= 5y + 1
-2x + 9y = -1
-2(5y + 1) + 9y = -1
-10y - 2 + 9y = -1
-y - 2 = -1
-y = 1
y = -1
x + 5 = 1
x = -4
(-4, -1)
