If f(x)=3x, what is f^-1(x)?

2 answers:

5 0

Answer: f-1(x) = x/3 + 5/3

Step-by-step explanation: The inverse function is found by replacing the independent variable with the dependent variable and vice versa like so

f(x) = 3x-5 becomes x = 3y-5; now we solve for y

3y = x +5 or y = x/3 + 5/3

Therefore the inverse function becomes: f-1(x) = x/3 + 5/3

Graph the function, identify if it represents exponential growth or decay, and identify domain and range. See picture

Brrunno [24]

Answer:

a. Decay

b. 0.5

c. 4

Explanation:

If we have a function of the form

$y=ab^x$

then

a = intital amount

b = growth / decay rate factor

x = time interval

If b > 1; then the equation is modelling growth. If b < 0, then the equation is modelling decay.

Now in our case, we have

$y=4(\frac{1}{2})^x$

Here we see that

inital amount = a = 4

b = 1/ 2 < 0, meaning the function is modeling decay

decay factor = b = 1/2

Therefore, the answers are

a. Decay

b. 0.5

c. 4
