What is the inverse of the function? f(x) = 2x - 10?
gulaghasi [49]

Answer:

Step-by-step explanation:

Let f(x)=y

y=2x-10

Switch x and y,

x=2y-10

x+10=2y

(x/2)+5=y

So f^{-1}(x)=\frac{x}{2}+5

which of the following answer choices describes all the transformation found in the cubic function f(x)=-(x+2)3-5
Alona [7]
The cubic function is f(x) = x^3

You need to perform three transformations to the cubic function to obtain
f(x) = - (x + 2)^3 - 5.

Those transfformations are:

1) Shift f(x) = x^3,  2 units leftward to obtain f(x) = (x + 2)^3

2) reflect f(x) = (x + 2)^3 across the x-axis to obtain f(x) = - (x + 2)^3

3) shift f(x) = - ( x + 2) ^3, 5 units downward to obtain f(x) = - (x + 2)^3 - 5

Answer:

√7

Step-by-step explanation:

2/5, 0.404040 and 0.286 are all rational as they all can be expressed in fraction form (0.4040 can be expressed as 40/99 and 0.286 as 286/1000 (can simplify but I didn't)) sqrt7 is the only irrational number.
