For this case we have the following linear function:
[tex]y = 2x-4
[/tex]
What we must do is equal the function to zero or equivalently, substitute the value of y = 0 in the given function.
We have then:
[tex]2x - 4 = 0
[/tex]
From here, we clear the value of x.
We have then:
[tex]2x = 4
x = 4/2
x = 2[/tex]
Answer:
all real zeros of the function y = 2x-4 are:
x = 2
