1) function f(x)
x - 5
f(x) = ----------------
3x^2 - 17x - 28
2) factor the denominator:
3x^2 - 17x - 28 = (3x + 4)(x - 7)
x - 5
=> f(x) = -----------------------
(3x + 4) (x - 7)
3) Find the limits when x → - 4/3 and when x → 7
Lim of f(x) when x → - 4/3 = +/- ∞
=> vertical assymptote x = - 4/3
Lim of f(x) when x → 7 = +/- ∞
=> vertical assymptote x = 7
Answer: there are assympotes at x = 7 and x = - 4/3

y = 27
Answer:
Step-by-step explanation:
Parts + 3($40 labor)=183.30
parts + 120=183.30
parts=63.30 but it includes tax. To find costs of parts before tax you
63.30/1.055=60 so parts are $60
or to solve with one equation:
parts(1.055) + 3($40 labor) = 183.30
parts(1.055) + 120=183.30
parts(1.055)=63.30
Parts = 63.30/1.055
parts = 60

Answer: ![\bold{f^{-1}(x)=\dfrac{2x-1}{2+x}}](https://tex.z-dn.net/?f=%5Cbold%7Bf%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B2x-1%7D%7B2%2Bx%7D%7D)
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's and then manipulate the equation to solve for y.
![y=\dfrac{2x+1}{2-x}\\\\\\\text{Swap the x's and y's:}\\x=\dfrac{2y+1}{2-y}\\\\\\\text{Multiply both sides by 2-y}:\\x(2-y)=2y+1\\\\\\\text{distribute x into 2-y}:\\2x-xy=2y+1\\\\\\\text{subtract 1 from both sides and add xy to both sides}:\\2x-1=2y+xy\\\\\\\text{factor out y from the right side}:\\2x-1=y(2+x)\\\\\\\text{divide 2+x from both sides}:\\\dfrac{2x-1}{2+x}=y\\\\\\\text{Therefore, the inverse }f^{-1}(x)=\dfrac{2x-1}{2+x}](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B2x%2B1%7D%7B2-x%7D%5C%5C%5C%5C%5C%5C%5Ctext%7BSwap%20the%20x%27s%20and%20y%27s%3A%7D%5C%5Cx%3D%5Cdfrac%7B2y%2B1%7D%7B2-y%7D%5C%5C%5C%5C%5C%5C%5Ctext%7BMultiply%20both%20sides%20by%202-y%7D%3A%5C%5Cx%282-y%29%3D2y%2B1%5C%5C%5C%5C%5C%5C%5Ctext%7Bdistribute%20x%20into%202-y%7D%3A%5C%5C2x-xy%3D2y%2B1%5C%5C%5C%5C%5C%5C%5Ctext%7Bsubtract%201%20from%20both%20sides%20and%20add%20xy%20to%20both%20sides%7D%3A%5C%5C2x-1%3D2y%2Bxy%5C%5C%5C%5C%5C%5C%5Ctext%7Bfactor%20out%20y%20from%20the%20right%20side%7D%3A%5C%5C2x-1%3Dy%282%2Bx%29%5C%5C%5C%5C%5C%5C%5Ctext%7Bdivide%202%2Bx%20from%20both%20sides%7D%3A%5C%5C%5Cdfrac%7B2x-1%7D%7B2%2Bx%7D%3Dy%5C%5C%5C%5C%5C%5C%5Ctext%7BTherefore%2C%20the%20inverse%20%7Df%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B2x-1%7D%7B2%2Bx%7D)
