What should be changed to make the answer correct?

• the coefficient of x should be ¹/₃

• the coefficient of x should be 3

• the constant should be 4

• the constant should be 3

• the constante should be ³/₄

Find the inverse of f(x) = -4x - 12

• f^-1(x) = 4x - 3
• f^-1(x) = -1/4x - 3
• f^-1(x) = 1/4x + 3
• f^-1(x) = -4x - 3

Find the inverse of  $f\left(x\right)=x^2-5$  

•  $f^{-1}\left(x\right)=\sqrt{x}+5$   
  

•  $f^{-1}\left(x\right)=\ ^3\sqrt{x-5}$  

•  $f^{-1}\left(x\right)=\sqrt{x+5}$  

•  $f^{-1}\left(x\right)=x^2-5$  

•  $f^{-1}\left(x\right)=x^2+5$  

You will need to know this information to do the next few questions.

• I see that the x & y coordinates switch places to form the inverses of points.

• Read and pick the other option.

• (-3,-1)(-4,-2)(-8,-6)
• (1,3)(2,4)(6,8)
• (-1,-3)(-2,-4)(-6,-8)
