Which of the following equations represents a quadratic function?

The minimum qualifying score to join the cheer team is 202.

Step-by-step explanation:

the competitive team allows only top 4% of athletes

if team tryout to score a mean of 200 and a standard deviation of 10 then

our quadratic equation is given as  

in order to find that do we have the real roots of a quadratic equation , the discriminant must be greater or equal to 0. the discriminant is denoted by d and given by the formula

where b is the coefficient of the middle term containing x, a is the coefficient of the term containing and the c is the constant term.

hence we have

a = 1 , b = 5 and c = 7

to calculate d

Hence we see that the discriminant.
