If f(x) = |x + 8|, find f(–11). 19 –3 3 –19 2. if f(x) = |x – 5| + 3, find f(2). 4 11 0 6

Step-by-step explanation:

1) Plug in the number to the equation

f(-11) = |-11 + 8|

= |-3|

absolute value makes it positive so the answer is 3

2) Plug in the number to the equation

f(2) = |2 -5| +3

do the absolute value before adding the 3

|-3| + 3 =  3 + 3

= 6

1.   f(-11) = 3.

2.   f(2) = 6.

Step-by-step explanation:

Note the vertical lines around the x + 8 is the absolute value which is always positive.

f(x) = |x + 8| so f(-11) =  |-11 + 8|

= |-3|

= 3 (answer).

If f(x) = |x – 5| + 3, find f(2).

f(2) = | 2 - 5| + 3

= |-3| + 3

= 3 + 3

= 6 (answer)

23
