Question

Which is a zero of the function f(x)=2x−6 ?

Answer 1

Answer:

x=3

Step-by-step explanation:

Answer 2

Answer:

$x=3$

Step-by-step explanation:

The zero(s) of a function is whenever the graph crosses the x-axis.

So, to solve for the zeros of a function, we set the function equal to 0 and solve for x.

We have the function:

$f(x)=2x-6$

We will set f(x) equal to 0:

$0=2x-6$

And solve for x. Add 6 to both sides:

$2x=6$

Divide both sides by 3:

$x=3$

Therefore, a zero of our function is x=3 at (3, 0).

And we're done!
