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
Answer: A. 38.4
Step-by-step explanation:
Because...
12/3.75 is 3.2; 3.2× 12 is 38.4. do 12÷ 3.75 meaning 3.2 miles every hour multiplied by 12 to get 38.4 miles.
