Question

What is f(-5) if f(x) = l2x-1l + 10

Answer 1

f(x) = l2x-1l + 10

x = -5

f(-5) = l2*-5 - 1l + 10

        = l-10 - 1l + 10  = l-11l + 10 = 11 + 10 = 21

       = 21

Answer 2

Answer:

A. 21

Step-by-step explanation:

$f(x)$= $|2x-1|+10$; $f(-5)$

$f(-5)$=  $|2x-1|+10$

$=|-10-1|+10\\=|-11|+10\\=11+10\\=21$
