If f(x) = │(x² – 50)│, what is the value of f(-5)?
a) 75 b) 25 c) 0 d) -25 e) -75

• |(-5)^2-50|
  |25-50|
  |-25|
  25
  
  Ans=> b)25

• put the value of X=-5
  25-50=-25
  ans d. -25

• 50
  mode((-25)^2-50))=25
• 8 years agoHelpfull: Yes(0) No(1)
• b.25
  f(-5)=|25-50|=25
• 8 years agoHelpfull: Yes(0) No(0)
• f(-5)=|((-5)^2-50)|
  =|(25)-50|
  =|-25|
  = 25 ( since |-x|=x )

• f(-5) = |(-5)(-5) - 50| = |25-50| = |-25| = 25 due to modulus sign

• ans is 25, bcoz |(-5)^2 - 50)| then the value is |25 -50| then is will ||-25|
  and we all know mod behaviour so the value will have to 25.
