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

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
