Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
i need D and E solution
![Let f be a function from A to B. Let S be a subset of B.
We define f(S). the inverse image of S as follows:
f (S) = {a € A| f(a) E S}
Now let g : R → R, h : R → R be functions where
g(x) = 1 +1 and h(x) = [x].
