Select the correct answer.<br> Find the Inverse of function A<br> F(x)=1/3 -1/2x

kompoz [17]

Answer:

If you actually meant f(x)=2x+3x−1 ,

then note it can be rewritten as:

f(x)=2x−2+5x−1=2+5x−1=y

At this point you can find x in terms of y (“make x the subject”):

y−2=5x−1⟹1y−2=x−15

⟹x=5y−2+1=y+3y−2

Switch variables back to x, and you have the inverse function of f:

g(x)=x+3x−2

How do you know you’ve calculated correctly? The composition of f with g should result in x — that is, evaluate f(g) and you should get the result x:

To which interval would we restrict f(x) = cos (x-π/4) so that f(x) is invertible?

nadezda [96]

Answer:

The range of x values for which y is unique is 2·π

Step-by-step explanation:

For a function j: X → Y to be invertible, we have that for every y in Y, there is associated only one x which is an element of x

Hence, f(x) = cos(x - π/4) gives

the x intercept at two penultimate points of the graph of cos(x - π/4) are;

x = 2.36, and x = 8.64

x = 3/4·π, and x = 2.75·π = $2\tfrac{3}{4}\cdot \pi$

Hence the range of x values for which y is unique is presented as follows

$2\tfrac{3}{4}\cdot \pi - \frac{3}{4}\cdot \pi = 2}\cdot \pi$

The range of x values for which y is unique = 2·π.
