Question

Does anyone know this?

Answer 1

There are two inputs for which the output is 5.

The vertex of its graph is at (0,-2)

Explanation:

Answer 2

2nd

4th

5th

EXPLANATION

The given function is

`y = |x| - 2`

The value of this function cannot be negative: False.

y = |1| - 2=-1

Its graph has a V-shape. This is true because it is the graph of y=|x| shifted downwards by 2 units.

There is only one input for which this function is zero. False

both -2 and 2 will make this function zero.

There are two inputs for which this function is 5. True, x=7 and x=-7

The vertex is (0,-2). This is true because it is the graph of y=|x| shifted downwards by 2 units.
