Answer: y=2x+4 for parallel and y=-1/2x+1 1/2

Step-by-step explanation: you need to do an equation using the slope which you can find by using y2-y1/x2-x1

from there you have to use y-y1=m(x-x1)

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other

Given the functions expressed as:

$h(x) =\sqrt{2x+2}\\g(x)\frac{x^2-2}{2} \\$

In order to check whether they are inverses of each other, we need to show that h(g(x)) = g(h(x))

Get the composite function h(g(x))

$h(g(x))=h(\frac{x^2-2}{2} )\\h(g(x))=\sqrt{2(\frac{x^2-2}{2} )+2}\\h(g(x))=\sqrt{x^2-2+2} \\h(g(x))=\sqrt{x^2}\\h(g(x))=x$

Get the composite function g(h(x))

$g(h(x))=\frac{(\sqrt{2x+2} )^2-2}{2} \\g(h(x))=\frac{2x+2-2}{2}\\g(h(x))=\frac{2x}{2}\\g(h(x))=x$

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other

3/7,0.45,4/9 from least to greatest?

Vlad1618 [11]

So you do 4/9=3/7
You do 9 times 3 and 4 times 7
So it means 4/9 is bigger than that.oBviously 0.45 is bigger.
So the answer is 0.45>4/9>3/7
