Find all real zeros of the function y=2x-4

Ber [7]

For this case we have the following linear function:
$y = 2x-4
$
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:
$2x - 4 = 0
$
From here, we clear the value of x.
We have then:
$2x = 4

x = 4/2

x = 2$
Answer:
all real zeros of the function y = 2x-4 are:
x = 2
