What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)?

x=6

x=2

Step-by-step explanation:

Fortunately for us, the function is written in factorized terms, so it is easier to find its roots.

The roots are the values for the 'x' variables that makes the functions goes to zero.

They are x=6 and x=2, any of those value make the function equals zero, or in other words, they are the points of interception with the 'y' axis.

To obtain these value

lets study the following condition

(x-6) * (x-2)=0

The above is accomplish when (x-6)=0 or (x-2)=0

We have two independent equations from where we obtain that x=6 and x=2

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
