Answer:
(3/2, 5/2)
Step-by-step explanation:
The x value for the vertex of a parabola in the form y=ax^2+bx+c is -b/2a. The x value is then plugged into the function to find the y value.
∠1 and ∠3 as well as ∠5 and ∠7 are corresponding
∠2 and ∠7 are alternate
x=-7
add 4 to both sides. leaving you with x=-7
These should be right hopefully! Hope it helps!
I'd say the answer is C.
