In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, f(x) = y if and only if g(y) = x.
Answer:
-4/7, -1/3, -0.1, 0, 0.1
Step-by-step explanation:
Answer:
A=346.46
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving forA
A=1
4πd2=1
4·π·212≈346.36059
Uh yeah sure <span>the question can be answered by collecting data and where there will be variability in that data.</span> But you'd probably just give it a estimate :)
Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
