If f (x) = |x - 4| + 5, find f (1).

10

0

2

8

Step-by-step explanation:

The question is what is f (1) when f (x) = |x - 4| + 5?

Before we start, I want to mention that this function involves the absolute value. The absolute value is when a number is being described as the distance away from the number 0 on a line. When it comes to absolute values, the number is never a negative.

Fore example, |5| = 5, |-235| = 235

So let us go straight into the problem!

f (1) = | (1) - 4| + 5

f (1) = | (-3) | + 5

f (1) = 3 + 5

f (1) = 8

There you go! When we put in an x-value of 1 into the function we will get 8 as the output or outcome!

8

Step-by-step explanation:

you substitute (x) with 1 so the equation would look like this

f (x) = |1-4|+5 so the answer for this is 8 because 1-4 is 3 and 3+5 is 8
