Derive the inverse of the function, f-1 of f(x) = 7x+2

Mathematics
1 answer:
Georgia [21]3 years ago
7 0
Replace f(x) with y
switch x and y
solve for y
replace y with f^-1

so

y=7x+2
x=7y+2
x-2=7y
(x-2)/7=y
f^-1=(x-2)/7

inverse is
f^{-1}= \frac{x-2}{7}

I have $100. I spent $40 on a prize and $45 on food. How do I figure out what % is purchase is from the original amount I had?
Paladinen [302]
You could say that you spent (purchased) 85% of the money that you had.

You spent a total of $85.

If you create the fraction 85/100, that is the same as saying you spent 85% of the money.

ALGEBRA HELP!! Write an exponential function represented by the table.
marysya [2.9K]

Answer:

y=-50*0.2^x

Step-by-step explanation:

the formula for an exponential function is:

y=a*b^x

what do we multiply -50 by to get -10?

-50x=-10

x=-10/-50

x=1/5

x=2/10

x=0.2

This initial value here is -50, it is the first in the table

y=-50*0.2^x
