1. Find f(-2) if : *
f (x) = 4 |x – 4| + 2
-20
28
32
26

  34

f(-2) means inserting 'x = -2' into the equation.

x = -2

4*|-2 -4| +2

= 4*|-8| + 2

= 4*8 + 2

= 32 + 2

= 34

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the answer is 24
