Given that (-3,1) is on the graph of f(x), find the corresponding point for the function f(x-1)

Helen [10]

Answer:

(-2,1)

Step-by-step explanation:

So we are given f(-3)=1 since the point (-3,1) is on f(x).

We want to use this point to find a point on f(x-1).

Now,

f(-3)=1

and we want

f(x-1)=1

What would x need to be such that x-1 is -3.

x-1=-3

Add 1 on both sides:

x=-3+1

x=-2

x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.

So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).

I know that f(x-1) would only be effecting our input because x-1 is the input.

Write the inverse function for the function, ƒ(x) = x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.

lesya [120]

The inverse is:

$f^{-1}(x) = x-4$

Further explanation:

Given function

$f(x) = x+4$

Step 1: Replacing f(x) with y

$y = x+4$

Step 2: Replacing x with y and y with x

$x = y+4$

Step 3: Solving the equation for y

$x = y +4\\x -4 = y+4-4\\y = x-4$

Step 4: Replacing y with f-1(x)

$f^{-1}(x) = x-4$

So, the inverse is:

$f^{-1}(x) = x-4$
