How can you use a point on the graph of f –1(x) = 9x to determine a point on the graph of f(x) = log9x?
Anastasy [175]

Whenever you can invert a function, you have that the graphs of f(x) and its inverse f^{-1}(x) are reflected with respect to the line y=x

So, given any point on the graph of f^{-1}(x), you can simply swap its coordinates to get the correspondent point on the original function f(x)

As an example, all exponential functions pass through the point (0,1), while all the logarithmic functions pass through the point (1,0)

A snail sets out on a 3 3/5 -mile journey, traveling at a speed of 2/65 miles per hour. a. How many hours will the journey take?
fiasKO [112]

Answer:a)117 hours b)4.875days.

Step-by-step explanation:

Using the formula

Speed =Distance / Time

Given Distance = 3 3/5 -mile

and Speed=2/65  miles per hour.

Time =Distance / Speed

Time = (3 3/5)/(2/65)

Time =18/5÷2/65

Time =18/5 x 65/2 =117 hours

Now 24 hours =1 day

therefore 117hours =(117hours x 1 day )/ 24 =4.875days.
