What is f(-3) if f(x)=|2x+1|+5
f(x)=|2x+1|+5
f(-3) = |2*-3 + 1|+5
= |-6 + 1|+5
= |-5|+5 = 5 + 5 = 10
f(-3) = 10
This answer is 10.
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.
