Answer:
a = h-7
Step-by-step explanation:
h = a+7
Subtract 7 from each side
h-7 = a+7-7
h-7 =a
The vertex is at (0, 3) so y=a(x-0)²+3, which is y=ax²+3
next, use a given point to find a: 10=a(3)²+3, so 9a=7, a=7/9
the equation is then y=

as for the first question, the shape is an ellipse, the domain is -5≤x≤5, the range is -3≤y≤3
the equation can be written as :
Hey there,
The answer is c
