The true statements are:

the y-intercept is y = 4.

All the other are false.

Which statements are true about this function?

Here we have the absolute value function f(x)= |x - 4|, let's find the characteristics.

The vertex is when the argument becomes zero, this happens at x = 4.

f(4) = |4 - 4| = 0

So the vertex is at (4, 0), meaning that:

The range is y ≥ 0

In x > 4 the graph increases.

in x < 4 the graph decreases.

To find the y-intercept we need to evaluate in x = 0

f(0) = |0 - 4| = 4

So the true statements are:
