Identify the quadratic equation with -1/3 and -1 as its roots.

x^2+(4/3)x+1/3

Step-by-step explanation:

In order to find the quadratic equation, you put the roots in this format:

(x-a)(x-b)=0

(x-(-1/3))(x-(-1))=0

(x+1/3)(x+1)=0

Then you would solve:

x^2+x+(1/3)x+1/3

= x^2+(4/3)x+1/3

Hope this helps!

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
