Is the relation a function? <br><br> {( 1, 12), (3, 14), (14, 3), (5, 12)}<br><br> yes or no

Iteru [2.4K]

Answer:

Yes.

Step-by-step explanation:

Yes because each value of x maps to a single value of y.

THere is a many-to-one relation with (1, 12) and (5, 12) but that is OK for a function. What would not be OK is if we had a one-to-many relation like (1, 12) and (1, 14) included in the ordered pairs - that is not a function.

If a polynomial function f(x) has roots -6 square root of -3, what must be a factor of f(x)

Lilit [14]

If a polynomial $f(x)$ has a root $x_0$ , then the polynomial is a multiple of $x-x_0$

In your case, we have $x_0=-6\sqrt{-3}$ , so the polynomial is a multiple of $x-(-6\sqrt{-3})=x+6\sqrt{-3}$
