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 :
Answer:
<em><u>The</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>k</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>44</u></em><em><u>.</u></em>
Step-by-step explanation:
1) Subtract 3 from both sides.

2) Simplify 14 - 3 to 11.

3) Multiply both sides by 4.

4) Simplify 11 × 4 to 44.
