Given the functionf(x)=0.5(3)^x, what is value of f-1(7)
gogolik [260]
Ok, a fun hack

if f⁻¹(a)=b then f(b)=a

so if f⁻¹(7)=b then f(b)=7

to find b, find x such that f(x)=7


7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides
log_3(14)=x

f^{-1}(7)=log_3(13)

Each day, a salesperson earns $25 plus 5% of their total sales for the day. The salesperson's goal is to earn more than $50 on T
Lera25 [3.4K]

The true statement about the inequality is that Total sales per day is greater than $250

<h3>How to write and solve inequality equation?</h3>

  • Total sales per day = x

  • Amount earned per day = 25 + 5% of x

= 25 + 0.05x

  • Thursday = 4th day of the week

The inequality:

4(25 + 0.05x) > 50

100 + 0.2x > 50

100 - 50 > 0.2x

50 > 0.2x

x > 50/0.2

x > $250
