What is the inverse of [tex] x^{2} -2?

Mnenie [13.5K]

Assuming you want the inverse of f(x)=x²-2,

f(x)=x²-2
repalce f(x) with y
y=x²-2
switch x and y
x=y²-2
solve for y
x=y²-2
x+2=y²
√(x+2)=y
replace y with f⁻¹(x)
f⁻¹(x)=√(x+2)

the inverse is √(x+2)

Mark Ronnie and Lisa bought a 75 inch curved 4000 television.Lisa put 650 more than Mark had.Mark had twice as much and then Ron

Alexeev081 [22]

So since you gave all of the equations of everyone's amount that they put in, it saves some work.

Let's add up everyone's contribution and then solve for x:

$(2x+500)+x+(650+2x+500)$

Then since we know the television costs $2,000, we can set this expression equal to that and simplify terms. Then we can solve for x:

$5x+1,650=2000$

$5x=350$

$x=70$

So since Ronnie put in 'x', we can say that Ronnie paid $70.

Since Mark put in '2x + 500', we can plug in 70 for x to find that Mark paid $640.

And since Lisa put in '650 + 2x + 500', we can plug in 70 for x again to find that Lisa paid $1,290.

1/X 1/4=7/12 solve and check solution

liraira [26]

$\frac { 1 }{ x } +\frac { 1 }{ 4 } =\frac { 7 }{ 12 } \\ \\ \frac { 1 }{ x } =\frac { 7 }{ 12 } -\frac { 1 }{ 4 }$

$\\ \\ \frac { 1 }{ x } =\frac { 7 }{ 12 } -\frac { 3 }{ 12 } \\ \\ \frac { 1 }{ x } =\frac { 4 }{ 12 } =\frac { 1 }{ 3 } \\ \\ 3x\cdot \frac { 1 }{ x } =\frac { 1 }{ 3 } \cdot 3x\\ \\ x=3$
