Answer:
f(x) = -5x - 4
Step-by-step explanation:
We want to get the inverse of the following function:
f^-1(x) = (-1/5)x - 4/5
To do that, we have to replace x with f(x) and f^-1(x) with x, as follows:
x = (-1/5)f(x) - 4/5
And then solve for f(x), the inverse of f^-1(x).
x + 4/5 = (-1/5)f(x)
f(x) = -5x + (-5)4/5
f(x) = -5x - 4
To check our result we compute a pair (x, f(x))
x f(x)
1 -5*1 - 4 = -9
which has to be equivalent to (-9, 1) in the original function
x f^-1(x)
-9 (-1/5)*(-9) - 4/5 = 1
Answer:
B) 1
Step-by-step explanation:
The smallest integer larger than 0.6 is 1.
___
The funny single-ended brackets signify the "ceiling" function. If the bent end is at the bottom, the "floor" function is indicated. The "ceiling" function returns the smallest integer not less than the given value. The "floor" function returns the largest integer not greater than the given value.
These are more commonly used than you might think. For example, the charge in a parking lot may be for a number of hours or fraction thereof. That is an expression of the ceiling function applied to hours. In this problem, that would mean that parking for 0.6 hours would be charged as 1 hour.
Parallel lines don't exist in elliptical geometry because elliptic geometry, a special case of Riemannian Geometry, is a non Euclidean geometry, in which, given a line L and a point P outside L, there exists no parallel lines because all the elliptical lines intersect.
