3) Vertex: (-7, 0) Axis of Symmetry: x=-7
6) Vertex: (-2, -1) Axis of Symmetry: x=-2
So you question is most likely about a triangle DEF with the 3 angles being named D, E, F. The triangle would look something like the image attached below.
If that is what is being asked then i need more info to answer but
By Definition it would be 180 degrees.
Answer:
y=-|x+1|+1
Step-by-step explanation:
It's an absolute value function vertically flipped and shifted 1 unit to the left, 1 unit to the the top.
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
