What is the equation of the parabola that has its vertex at (7,6) and contains the point (6,8)? Question 10 options: A) y = 2x2 – 28x + 52 B) y = x2 – 14x + 52 C) y = 2x2 – 28x + 104 D) y = 2x2 – 14x + 104

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

this cant be answered without the graph. you may need to add it.
