Given f(x)=-1/7√16-x^2 find f^-1(x)

Vera_Pavlovna [14]

Answer:

$f^{-1}(x)=\pm \sqrt{49x^2-16}$

Not a function.

Step-by-step explanation:

The given function is;

$f(x)=-\frac{1}{7}\sqrt{16-x^2}$

Let $y=-\frac{1}{7}\sqrt{16-x^2}$

Interchange x and y;

$x=-\frac{1}{7}\sqrt{16-y^2}$

Solve for y;

$-7x=\sqrt{16-y^2}$

Square both sides

$(-7x)^2=(\sqrt{16-y^2})^2$

$49x^2^2=16-y^2$

$49x^2^2-16=y^2$

$y=\pm \sqrt{49x^2-16}$

The inverse is

$f^{-1}(x)=\pm \sqrt{49x^2-16}$

$f^{-1}(x)=\pm \sqrt{49x^2-16}$ is not a function because one x-value maps onto to different y-values.

You have set up a webpage for your company. your logo took up 2/7 of your allotted space on the main page and the location infor

Maksim231197 [3]

So we want to find how much more space the logo took up.

So just subtract the location info from the logo space.

2/7 - 1/10

To subtract, you just want to find a common denominator. In this case it would be 70.

2/7 * 10/10 - 1/10 * 7/7

20/70 - 7/70

Then just subtract.

13/70

So that's the fraction. For the percent, just divide.

13/70 = 0.186 ish

Or, 18.6% ish

How do I solve for X if I have something like this?<br>(x+2)(1-x)= -4

lakkis [162]

(x+2)(1-x)=-4

subtract 2 from both sides: x(1-x)=2

simplify:x-2x=2

subtract: -x=2

switch the negatives

x=-2
