Pranav · Answer 1

if f (x) = |2x - 1| - 5

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

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

f (-3) = |-7| - 5

f (-3) = 7 - 5

f (-3) = 2

Delilah Cuevas · Answer 2

To answer this question, plug - 3 in for X : (Remember that the | symbol means absolute value)

f (-3) = |2x - 1| - 5

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

f (-3) = |-7| - 5

f (-3) = 7 - 5 Absolute value of - 7 = 7

f (-3) = 2
