Question

ANSWER ASAP!!!!! Evaluate ƒ(x) = |3x – 2| for ƒ(–5) and ƒ(7). Question 7 options: A) ƒ(–5) = 8, ƒ(7) = 7 B) ƒ(–5) = 12, ƒ(7) = –2 C) ƒ(–5) = –17, ƒ(7) = 9 D) ƒ(–5) = 17, ƒ(7) = 19

Answer 1

Answers:

• f(-5) = 17
• f(7) = 19

====================================

Work Shown:

Plug in x = -5. Use PEMDAS to simplify

f(x) = |3x-2|

f(-5) = |3(-5)-2| ... replace every x with -5

f(-5) = |-15-2|

f(-5) = |-17|

f(-5) = 17

---------------------

Repeat for x = 7

f(x) = |3x-2|

f(7) = |3*7-2| ... replace every x with 7

f(7) = |21-2|

f(7) = |19|

f(7) = 19
