F(x) = 2x - 6
y = 2x - 6
2x - 6 = y |add 6 to both sides
2x = y + 6 |divide both sides by 2
x = 1/2y + 3
f^{-1}(x) = 1/2x + 3
f^{-1}(2) = 1/2 · 2 + 3 = 1 + 3 = 4
Answer: b. 4
Answer:
A
Step-by-step explanation:
The n th term ( explicit formula) for a geometric sequence is
f(n) = a
where a is the first term and r the common ratio
Here a = 2 and r = - 8 ÷ 2 = - 4, thus
f(n) = 2
I think the answer would be 0.08
Answer:
12x
Step-by-step explanation:
number 1 is 12x bcuz two x plues ten equals 12x although i did it another way i still got it right just letting you no im working on the second one
