What’s the inverse of <br> f(x) = -2 + 2/3x
saveliy_v [14]

So the steps to find the inverse are:

  1. Change f(x) to y
  2. Switch the positions of x and y
  3. Solve for y
  4. Change y to f^-1(x)

f(x)=-2+ \frac{2}{3}x\\\\y=-2+ \frac{2}{3}x\\\\x=-2+ \frac{2}{3}y

Now let's solve for y as such:

x=-2+ \frac{2}{3}y \\\\x+2=\frac{2}{3}y\\\\\frac{3}{2} (x+2)=y\\\\\frac{3}{2}x+3=y\\\\\frac{3}{2}x+3=f^{-1}(x)

<u>Your inverse is f^-1(x) = 3/2x + 3</u>

  • 6 \sin(x)  - 3 \sqrt{2}  = 0

  • 6 \sin(x)  = 3 \sqrt{2}

  • \sin(x)  =  \dfrac{3 \sqrt{2} }{6}

  • \sin(x)  =  \dfrac{ \sqrt{2} }{2}

  • \sin(x)  =  \dfrac{1}{ \sqrt{2} }

\large\boxed{x = 45° \:  \: or \:  \: 135°}
