Question

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

Answer 1

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

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

= |-6 + 1|+5

= |-5|+5 = 5 + 5 = 10

f(-3) = 10

Answer 2

This answer is 10.

Step-by-step 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.
