Switch where the x and y are, then solve for y. f(x) = y.
x = 3y^2 + 6
x-6 = 3y^2
(x-6)/3 = y^2
f^-1(x) = y = sqrt((x-6)/3)
The second and third one are correct
The coefficient is 2 (it is always the number before the variable)
<u><em>Answer:</em></u>
The height of the parallelogram is 33 ft
<u><em>Explanation:</em></u>
<u>The area of the parallelogram can be calculated using the following rule:</u>
Area of parallelogram = base * height
<u>In the problem, we are given that:</u>
Area = 544.5 ft²
Base = 16.5 ft
<u>Substitute with the given values in the above equation and solve for the height as follows:</u>
Area = base * height
544.5 = 16.5 * height

Hope this helps :)
