Richiez: help me please, show the workings if f(y-4)=y²+2y+3, then find f(2) |
Re: Nairaland Mathematics Clinic by dejt4u(m): 2:03pm On Jul 01, 2015 |
SuperNover:y - 4 = 2, y = 6, then, f(2) = 6² + 2(6) + 3, = 36 + 12 + 3, = 51 |
Re: Nairaland Mathematics Clinic by Nobody: 3:28pm On Jul 01, 2015 |
dejt4u: you made a little mistake. 2(6)= 12 |

let a function f be defined by x^2-2x-3/x^2+2x+3 hence :determine the domain of f(x) , find the range of f(x) , find an expression for f(3x+1) and hence determine f(4) |

help me out my fellow mathematicianlet on these question : A function f be defined by x^2-2x-3/x^2+2x+3 hence :determine the domain of f(x) , find the range of f(x) , find an expression for f(3x+1) and hence determine f(4) |

pls help me solve this question i need it urgently :let a function f be defined by f(x)=x^2-2x-3/x^2+2x+3 hence determine the domain of f(x) ,find the range of f(x) , find an expression for f(3x+1) and hence determine f(4) |
Re: Nairaland Mathematics Clinic by naturalwaves: 6:56pm On Jul 03, 2015 |
abiodun3934:Modified: Domain is.....All real numbers Except ( - 1+i/2*sqrt 8 ) and ( - 1-i/2*sqrt8). The first (-i) entries in the solution is a mistake. Meant to write - 1.

A woman is four times old as her daughter. In four years time she will be three(3) times old as her daughter. What are their ages? Naturalwaves, dejt4u and others help plzz! Been solving it over and over since yesterday but my answer doesn't seem to be correct |
Re: Nairaland Mathematics Clinic by dejt4u(m): 6:38pm On Jul 04, 2015 |
Peezzy:Let the woman's age be w and that of the daughter is d equation1; w = 4d equation 2; w+4 = 3(d+4), putting eqn 1 in eqn 2, 4d+4=3(d+4), 4d+4=3d+12, d=8 since w=4d, w=32 the woman is 32years old and the daughter is 8years old.. Shalom 1 Like |

toobby: given a= 3 , a+4d=9 => 3+4d=9 =>4d=6 d=6/4=3/2 now the series goes thus first term. , a=3 second term, a+d=> 3 +3/2 =(6+3)/2 = 9/2 third term , a+2d , => 3 +2(3/2) = 3+3=6 fourth term , a+3d , =>3+3(3/2) =(6+9)/2 = 15/2 firth term , a+4d , => 3+4(3/2) =3+6 =9 Now. though my boss above have done Justice so far. but re-check the question from " if the sum is 8" are you sure its 8? |

Re: Nairaland Mathematics Clinic by agentofchange1(m): 5:14pm On Jul 05, 2015 |
aman2: the proofs are quite cheep sha , but kinda long (though I could summarize.) Simpsons rule gives a better approximation over trapezoidal we use S-1/3 ...for ....Even n we use. S-3/8 . for n being multiple of 3 ( n= data point ) we use trapezoidal rule for close step size but they're cases where n is neither even nor multiple of 3 ( I.e prime n ) , for such case , we combine S -1/3 & S-3/8 (step size , s= (x-x0)/h here S-1/3. => h/3[ £wf*f(x)] S-3/8 => 3h/8[£wt*f(x)] T.R= h/2 [£wt.*f(x)] £= sigma notation for summation where h= interval ; wt.= wight factor ( for S-1/3 => 1 4 2 4 2 4 2 . . .1 , for S-3/8 => 1 3 3 2 3 3 2. . .1, for T.R..=> 1 2 2 2 2 . . .1 ) f(x)= given function . guess that's it. |
