What is the inverse of f if f (x) = ^3 sqrt x-7

=

Step-by-step explanation:

Given f(x) =∛(x-7)

To find the inverse we have to make x as subject

Let f(x)= y

y=∛(x-7)

Taking cube both sides

y³=(∛(x-7))³

y³=x-7

Adding 7 both sides

y³+7=x-7+7

x=y³+7

Here we replace x with y and y with x

i.e. y=x³+7

Therefore =

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
