Answer:
f⁻¹(7) = 1
Step-by-step explanation:
Step 1: Write out function
f(x) = 3x + 4
Step 2: Find f⁻¹(x) (or known as inverse f(x))
y = 3x + 4
x = 3y + 4
-3y + x = 4
-3y = 4 - x
y = -4/3 + x/3
Step 3: Plug in 7 into inverse f(x)
f⁻¹(7) = 7/3 - 4/3
f⁻¹(7) = 3/3
f⁻¹(7) = 1
If you have 15% off that means you should only pay 100 - 15 = 85% of the price so the answer is:
?/46 = 85/100
so ? is the price that you should pay:
85*46 /100 = $39.1 :)))
i hope this is helpful
have a nice day
