Find the inverse function. f (x)=1/2x+6
Lana71 [14]

The inverse of this function is f(x) = 2x - 12.

You can find the inverse of any function by switching the f(x) and x values in the equation. Then you can solve for the new f(x) value. The result is your inverse function. The work for this one is below.

f(x) = 1/2x + 6 ----> switch f(x) and x

x = 1/2f(x) + 6 ----> subtract 6

x - 6 = 1/2f(x) ----> multiply by 2

2x - 12 = f(x) ----> change the order for consistency.

f(x) = 2x - 12

Consider function f.
MariettaO [177]

Answer:

  • x = 2, x = -1, x = -3
  • As x approaches negative infinity, f(x) approaches negative infinity

Step-by-step explanation:

<u>Given function</u>

  • f(x)= x^3 + 2x^2 - 5x - 6

<u>Finding zero's</u>

  • x^3 + 2x^2 - 5x - 6 = 0
  • x^3 - 2x^2 + 4x^2 - 8x +3x - 6 =
  • (x - 2)(x^2 + 4x + 3) =
  • (x - 2)(x^2 + x + 3x + 3) =
  • (x - 2)(x(x + 1) + 3(x + 3)) =
  • (x - 2)(x + 1)(x + 3)

<u>Zero's are</u>

  • x = 2, x = -1, x = -3

<em>See the graph attached</em>

<u>Correct end behavior as per graph:</u>

  • As x approaches negative infinity, f(x) approaches negative infinity
