Question

What is f(-3) if f(x)=|2x+1|+5

Answer 1

Answer

This answer is 10.

Explanation

Step by step solution is as follows:

$f ( x) = |2x + 1| +5$

For x= -3

$f (-3) = |2(-3) + 1| +5$

$f (-3) = |2. (-3) + 1| +5$

$f (-3) = |-6 + 1| +5$

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

By applying absolute value

$f (-3) = 5 +5$

$f (-3) = 10$

So the answer of given question is 10.

Answer 2

f(x)=|2x+1|+5

f(-3) = |2*-3 + 1|+5
    
        = |-6 + 1|+5
   
        = |-5|+5  = 5 + 5 = 10

f(-3) = 10
