Determine whether f(x)=5x+1/x and g(x)=x/5x+1 are inverse function. EXPLAIN how you know?

1 answer:

8 0

Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.

We only have to do this for 1 of the functions so we will take f(x)

x = 5y +1/y

I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)

Answer:

Jim - Ocean, because lakes don't have waves to surf on. Oceans do.

Darrell - Lake, because it's the only other water option.

Janet - Mountains, because Stephanie doesn't live in the mountains.

Stephanie - Desert, because it's the only one left.

Hope I could help!

<h2>Explanation:</h2><h2></h2>

Let's solve this problem graphically. Here we have the following equation:

$sin^{-1}(4x) + sin^{-1}(3x) = -\frac{\pi}{2}$

So we can rewrite this as:

$f(x)=sin^{-1}(4x) + sin^{-1}(3x) \\ \\ g(x)= -\frac{\pi}{2}$

So the solution to the equation is the x-value at which the functions f and g intersect. In other words:

$f(x)=g(x) \\ \\ sin^{-1}(4x) + sin^{-1}(3x) = -\frac{\pi}{2}$

Using graphing calculator, we get that this value occurs at:

$\boxed{x=-0.2}$

When we say "split the cost evenly", what are you actually doing?

xz_007 [3.2K]

You basically just split it right down the middle. if the cost of something is lets say $75.58, then you would divide 75.58 by 2, which is $37.79
