For the function f(x) -4 sqrtx - 1, find the inverse function.

Step-by-step explanation:

We have the function: and we have to find the inverse.

Observation: , then

You can obtain the inverse of a function by switching the x and y values. This means:

We're going to call . Now we have to clear "y'".

First we have to add (1) in both sides of the equation:

Now divide in (-4) both sides.

And for our last step we have to square both sides:

Then the third option is the correct:

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
