The answer:
-7 3/4, -7.6, -6 7/8, 32/5, 6.9
X^6 - 8, because it is (x^2)^3 - 2^3
The answer is =
Any number divided by itself = 1
57000 / 12 = $4750 monthly (before taxes)
Your answer is √(x + 4).
A strange way to find the inverse of a function is to write it first as y = x² - 4, and then to switch the y and x around to get x = y² - 4. Then you just solve for y, so:
x = y² - 4
+ 4
x + 4 = y²
√
√(x + 4) = y
I hope this helps!
