Question

Y = |x|+ 4
Determine the value of y if x is -4

Answer 1

Answer: when x is -4, the value of y is 8.

Explanation:

To determine the value of y when x is -4, we substitute -4 for x in the equation:

y = |x| + 4

y = |-4| + 4

The absolute value of -4 is 4, so:

y = 4 + 4

y = 8

Therefore, when x is -4, the value of y is 8.

Answer 2

y = 8

Explanation:

The question is asking us to find the value of y.

In the equation
`\sf+4`, we need to take the absolute value of x, which is -4:

`\sf+4`

Recall that the absolute value of any number is the positive of that number. That means that the absolute value of -4 is the positive of -4, which is 4.

`\sf{y=4+4}`

`\sf{y=8}`

Therefore, y = 8.
