Question

Which describes all possible values of f(x) in the function f(x) = √x/2? All real numbers all real numbers except for 0 all positive real numbers and 0 all negative real numbers and 0

Answer 1

all positive real numbers and 0

Explanation:

The function has a square root in the x value, so this function can't have negative values, because a negative value of x would give a complex number for f(x), and positive values of x gives positive values of f(x).

The function f(x) can be zero, if the value of x is zero:

`f(0) = √(0) /2 = 0/2 = 0`

So the function f(x) can only have positive values and the value 0.

Correct option: "all positive real numbers and 0"
