If f(x) = 11x – 5, then f^-1(x)=
MAVERICK [17]

Answer: f^-^1(x)=\frac{x+5}{11}

Step-by-step explanation:

To find the inverse, you replace the x with y, and y with x.

x=11y-5                       [add 5 on both sides]

x+5=11y                       [divide both sides by 11]

\frac{x+5}{11} =y

f^-^1(x)=\frac{x+5}{11}

Find the root(s) of f (x) = (x + 5)3(x - 9)2(x + 1). -5 with multiplicity 3 5 with multiplicity 3 -9
faust18 [17]

Answer:

  -5, multiplicity 3; +9, multiplicity 2; -1

Step-by-step explanation:

The roots of f(x) are those values of x that make the factors be zero. For a factor of x-a, the root is x=a, because a-a=0. If the factor appears n times, then the root has multiplicity n.

f(x) = (x+5)^3(x-9)^2(x+1) has roots ...

  • -5 with multiplicity 3
  • +9 with multiplicity 2
  • -1
