Answer:

(2)

Step-by-step explanation:

Let f(x) = y → f-¹(x) = f(y) = x, f(y) is the inverse of f(x)

Thus,

=> -x³ - 9 = y

=> - y - 9 = x³

=> (-y - 9)^(1/3) = x

=> f(y) = x

Inverse is (-y-9)^(1/3)

Replacing the variable, inverse is (-x-9)^(1/3)

notsponge [240]

Answer:

y = 3x - 1

Step-by-step explanation:

Let's start with the two points.

y = mx + b

-19 = -6m + b

5 = 2m + b

Subtract the first from the second.

24 = 8m

m = 3

5 = 2*3 + b

b = -1

On the plane curve defined by the parametric equations below, what point corresponds to t= -1
Anton [14]
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.

That is:  x = 2(-1) - 1
                 = -2-1 
                = -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
 
  y = (-1)∧-3
    = -1

The point that correspond to t=-1 is (-3,-1).
