Consider the functionf:R→Rdefined viaf(x) =|x|.(a) Give a functiongwith domainRsuch thatg◦fis one-to-one, or describe why it is

yaroslaw [1]

Answer:

(a) Is not possible

(b) It is possible

(d) Is NOT possible.

Step-by-step explanation:

(a)

Is not possible, notice that for any function $g$ such that

$g : \mathbb{R} \rightarrow \mathbb{R}$

you would have that

$(g\circ f)(x) = g(f(x)) = g(|x|)$

And for, lets say -3,3 you have that

$g(|-3|) = g(|3|) = g(3)$ therefore is not possible to find a function that is one to one.

(b)

It is possible. Take the following function

$g(x) = x\sin(x)$ since $\sin$ is periodic it will take positive and negative numbers and if you multiply by $x$ each period will become bigger and bigger.

(c)

It is possible. Take the function

$g(x) = \sqrt{x}$

Then

$(f \circ g )(x) = | \sqrt{x} | = \sqrt{x}$ and $\sqrt{x}$ is one to one.

(d)

It is NOT possible because $(f\circ g)(x) = f(g(x)) = |g(x)|$ and that will always be positive.

Katrina needs 3/5 kilogram of flour for a recipe. Her mother has 3/7 kilogram of flour in her pantry. Is this enough flour for t

almond37 [142]

No, if you convert 3/5 and 3/7 into like fractions, you would get 3/5=21/35 and 3/7=15/35 therefor, you will need 6/35 kilogram more flour.
