Find the inverse of the given function.<br><br> f(x) = -1/2√x + 3, x ≥ -3
inna [77]
<span>Find the inverse of the given function.

f(x) = -1/2√x + 3, x ≥ -3

I will have to assume that you meant f(x) = -(1/2)sqrt(x) + 3.  If you actually meant f(x) = -(1/2)sqrt(x+3), then obviously the correct result would be different.

1.  Replace "f(x)" by "y:"  y </span>= -(1/2)sqrt(x) + 3
 2.  Interchange x and y:  x = -(1/2)sqrt(y) + 3
3.  Solve for y:  x-3=-(1/2)sqrt(y), so that 2(3-x)= sqrt(y) and y=+sqrt(2[3-x])
4.  Replace "y" with 

           -1
        f      (x) = sqrt(2[3-x])

Here, there are restrictions on x, since the domain of the sqrt function does not include - numbers.  The domain here is (-infinity,3]

A function h(x) is defined by the equation h(x) = sqrt x-2 + 3. Which is the graph of h(x)?
____ [38]
<h3><u>Explanation</u></h3>
  • Given Equation

h(x) =  \sqrt{x - 2}  + 3

  • Transformation

A constant inside the square root will make the graph shift either left to right, depending on the number. From the equation. The graph shifts to right two units.

A constant outside the square root will make the graph shift up or down, depending the value. From the equation, the graph shifts up 3 units.

<h3><u>Answer</u></h3>
  • Second Image, the first one where x = 2 and y = 3.

a bottling machine can fill 300 bottles in 5 minutes at this rate how many bottles can be filled in 8 minutes
kirill [66]
480 bottles because 300 divided by 5 is 60 so then you multiply 60 by 8 and you get 480!

Choose the correct simplification of the expression (3x)^4.
Y_Kistochka [10]
The exponent 4 needs to be applied to both 3 and x, so we would have:
3 * 3 * 3 * 3 * x^4.
9 * 9 * x^4.
81x^4
