Answer:
Explanation:
We are asked to find f(4) for a function. We are finding the output or y-value when the input or x-value is 4.
Substitute 4 for x in the function.
Solve inside the absolute value signs.
The absolute value of a number is its distance from 0 on a number line. It is always the positive version of a number, so the absolute value of -3 is 3.
Add.
For the function f(x)= |x-7| +3, f(4) is equal to 6.
