Question

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

Answer 1

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
