23. Which functions have at least one real root? Check all that apply. Of(x) = -x2 + 10x – 14
O fx) = -x2 + 4
O Mx) = 2x2 - 12x + 18
I f(x) = -3x2 + x -2
f(x) = x2 – 3x + 25
O fx) = 10x2 - 4x

a² + b²= c²

24² + 7² = c²

c= 25

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
