if F(t) = (t^3-1)
G(f) = 1
H(t) = -t^2

Then find the value of
HOH(-2 ) + GOG(0) - FOF(1)



a. -15, b. -14,c. -16, d. -17

• ans is -14
  -16 + 1 - (-1)= -16+2= -14
• 8 years agoHelpfull: Yes(23) No(4)
• FOF(1)=-1
  GOG(0)=1
  HOH(-2)=-16
  HOH+GOG-FOF=-16+1-(-1)=-16+2=-14

• At x=1, F(x)=(1)^3-1=0
  FOF(1)=-1;
  at x=0, G(0)=1
  GOG(0)=1
  at H(-2)=-4
  HOH(-2)=-16
  So, from above -16+1=-15

• =>HOH(-2) + GOG(0) - FOF(1)
  =>H(H(-2)) + G(G(0)) - F(F(1))
  =>H(-(-2)^2) + G(1) - F(1^3-1)
  =>H(-4) + G(1) - F(0)
  =>-(-4)^2 + 1 - (-1)
  =>-16 + 1 + 1
  =>-14

• -16 is the answer

• -16 is right answer

• hey naveena ur ans is wrong as when we do squaring the negative sign automatically get converted to postive sign as u did wrong in case of HOH(-2)

• At x=1, F(x)=(1)^3-1=0
  FOF(1)=-1;
  at x=0, G(0)=1
  GOG(0)=1
  at H(-2)=-4
  HOH(-2)=-16
  So, from above -16+1-1=-16

• how it is possible as after squaring any negative no. it become positive then how -16 it should be +16

• No Shyna
  
  -X^2 = -1*X^2 hence H(-2) = -1 * (-2)^2 = -4

• HOH = -(-t^2))^2 => -(-(-2)^2)^2) => -16
  GOG = 0
  FOF = ((t^3)-1)^3) -1 => -1
  
  so -16 + 0 + (-1) = -17

• answer is -14
  HOH(-2)=-16

• HOH(-2) = H(-4)=-16
  GOG(0) = G(1) = 1
  FOF(1) = F(0) = -1
  H0H(-2)+GOG(0)-FOF(1)=-16+1-(-1) = -14

• -14
  H(H(-2))=H(-4)=-16
  G(G(0))=1 because g is a constant function
  F(F(1))=F(o)=-1
  -16+1-(-1)=-14
