Question

if f(x)=|x-1| and g (x) = 5x -4, then which of the following is false? (A) fog (x) =|5x-5| (B) gof (x) = 5|x-1| -4 (C) gog (1) = 4 (D) fof (-1) = 1

Answer 1

i got -4 for the c) part

Answer 2

Hi Julian....do u think (C) is right ans to the question, i'm confused

Answer 3

well make the operation
gog (1)
and see what u got
do u have problems finding gog (1)?

Answer 4

it's been a long long time i did maths? suddenly for computer programming it is required.....Thanx for ur help frnd....and did u check other options?

Answer 5

If f(x)= 5-x,then which of the following is false ?
(A) is strictly increasing in (0,
(B) is strictly decreasing in (0,
(C) is strictly decreasing in (- 0)
(D) =R(real numbers) =(0,

Answer 6

well maths is requeried even for programming
u have there some math operators
i think that the logic in math and programming is very similar
i check the oither options

Answer 7

increasing in (0, ??????

alphs=Infinite

Answer 11

that function is decreasing on its entire domain

Answer 12

that Means (B) Or (C) ?

Answer 13

R u there Julian?

Answer 14

If f(x)=|x+2| then,
(A) f(x+y)=f(x)+f(y) (B) f|x|=|f(x)| (C) f(xy)=f(x).f(y) (D) none of these
