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.

What is a solution of -8x+5>=11<br> A.-1/2<br> B.3<br> C.0.25<br> D.-1

Blababa [14]

Answer:

i got -2

Step-by-step explanation:

1 step; 8*x-5-(11)=0

2 step; 8x - 16 = 8 • (x - 2)

3 step; Solve : 8 = 0

4 step; Solve : x-2 = 0

final part Add 2 to both sides of the equation :

x = 2
