# null agency of functional value

Need the null set of functions y = 2x-8 y = x ^ 2-9

## The best answer

The first is a root x = 4 and at the 2nd x = 3 and x = -3. They're extremely easy ^^ Simply put and dissolve zero.

Y = 0 and x after dissolving. Where is the problem?

Think about what is zero? Iwas is NULL! Set times y = NULL !!! and solve times by X on !!!

... Then they calculate.

Do your homework alone!
