Find the domain of the function.
f(x) = -2x + 4
A. (-∞, 0) u(0, ∞)
B. (-∞, ∞)
C. [-4, ∞)
D. (0, ∞)
That is a straight line with slope -2, it has perfectly finite values for any real x
so
B
Thanks!!! :)
To find the domain of a function, we need to determine the set of all possible values for x that make the function defined. In this case, we have the function f(x) = -2x + 4.
Since there are no denominators or square roots involved, we don't have to worry about any restrictions on x. Therefore, the domain is all real numbers, which is represented as (-∞, ∞).
Therefore, the correct answer is:
B. (-∞, ∞)
