The vertex is (4,-4) and the other given point is (3,-2)

Find the quadratic equation

as if you are asking in terms of graph:-(4,-4) lies in quadrant 4th and (3,-2) lies in quadrant 4th only

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
