Answer:

x=34

Step-by-step explanation:

If you put Y and X <u>into a ratio</u> then it will be

5:2

because since their GCF is 11, then we will have to <u>divide</u> both of the numbers by <em>11</em>.

If y=85 then that means that it was<u> multiplied by 17</u>. If we want them to <u>stay within the same ratio</u>, then we will have to multiply X (2) by 17.

That will get you 34.

The function f(x)=(x-1)^4 is not one to one. However, if we restrict the domain to x greater than or equal to 0, we can find it'
nikklg [1K]

Answer:

Option A

Step-by-step explanation:

Domain should be greater than/equal to 1 for the function to be one-one.

f has vertex at (1,0)

f inverse has (0,1)

f(x) = 4

(x - 1)⁴ = 4

x = 2.414

On f: (2.414, 4)

On f inverse: (4, 2.414)
