We have
.
To find inverse function
we substitute x with
and vice-versa to get

Now solve for
. Note that I will use
instead.

So we find that
.
Hope this helps.
Answer:
a) Linear function
b) Linear function
c) Exponential function
d) Exponential function
Step-by-step explanation:
a) The number of hours in a day increases constantly with 60 minute intervals
b) Constant speed = same distance traveled per given time - so it's linear
c) If a population doubles every y years, it means that the population is being raised exponentially - not at a constant rate, but more each year
d) Same as c
2 ten dollar bills, 1 one dollar bill.
20*8= 160
186- 160 = 26
26 - 5 = 21
Answer:
2.4
Step-by-step explanation:
Answer:
y= 1/2x + 1
Step-by-step explanation:
Refer to y=mx+b, m=slope and b= y-intercept
First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half).
Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1.
Finally, put these in y=mx+b form:
y=(slope)x+(y-intercept) ---> y= 1/2x + 1
I tried my best to explain everything, I hope you found this helpful!
