The function f(x) = 2x - 6 has a zero of 3.

To find the zero of the function

f(x)=2x−6, we set

f(x) to zero and solve for

f(x)=2x−6

Setting f(x) to zero:

0=2x−6

To isolate x, add 6 to both sides of the equation:

0+6=2x−6+6

6=2x

Now, divide both sides by 2 to solve for x:


(2x)/(2) =
(6)/(2)

x=3

Therefore, the solution to f(x)=0 is x=3.

This means that 3 is the zero of the function, representing the value of x for which f(x) equals zero.

Substituting x=3 back into the original function verifies this:

f(3)=2(3)−6=6−6=0

Hence, x=3 satisfies the equation

f(x)=0, confirming that 3 is indeed a zero of the function

f(x)=2x−6.

Question

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