<h2>
1. y-intercept</h2>

The quadratic function
represents a parabola. In fact, the graph of a quadratic function is a special type of U-shaped curve called a parabola. To find the y intercept, we set
as follows:

<h2>
2. x-intercepts</h2>

To find the other x-intercept, we must set
as follows:

Therefore, the other x-intercept is
. You can see both the y-intercept and the x-intercepts in the figure below.
The 2 angles in a complement would be (in degrees) 65 and 25
Answer:
easey, sub them
(x,y)
see if true
(0,1), 2(0)+1>-4, 1>-4, true
(4,-12), 2(4)+-12>-4, 8-12>-4, -4>-4, false
(5,-12), 2(5)+-12>-4, 10-12<-4, -2>-4, true
(-1,-1), 2(-1)+-1>-4, -2-1>-4, -3>-4, true
(-3,0), 2(-3)+0>-4, -6>-4, false
answers are
(0,1)
(5,-12)
(-1,-1)
Hopefully that helped you a little bit :)
Seeing from the graph I've provided above, the correct answer would be D, the last one.
