F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)

Step-by-step explanation:
Answer:
the real answer is -1/3
Step-by-step explanation:
6lyl +6=4 subtract 6 from both sides
6lyl =-2 divide both sides by 6
lyl = -1/3
But absolute value is always a positive quantity, so this is impossible.....
Definitely 60 because it is the only one appearing not just once but twice in this sequence :)
Answer:
- sign = negative, degree = 5
Step-by-step explanation:
<u>The graph has negative leading coefficient as </u>
It is of the odd degree, and the degree is most probably 5
