Answer:
- inverse is not a function
- unless the domain is restricted to |x| ≥ 1.2 (approximately)
Step-by-step explanation:
The test to see if the inverse function is also a function is called the "horizontal line test." The test passes if any horizontal line intersects the graph in only one place.
Here, a horizontal line can intersect the graph in 1, 2, or 3 places, so the test fails. The function does not have an inverse that is a function.
__
If the domain of the inverse relation is restricted to |x| > 1.2, then that inverse will map any x to only a single value of y. Then it will be a function.
_____
The graph shows the original function (dashed red line) and the inverse relation (blue). The green shading marks values of x for which there is a single value of y, so the inverse relation is a function in those regions.
(We could be more specific as to the limits on the domain of f^-1(x), but the given graph seems to have an unknown vertical scale factor.)
Answer:
inches.
Step-by-step explanation:
Length of first ribbon inches.
Length of second ribbon inches.
To find the greatest length he can make of smaller strips that are all equal in length, we need to find the H.C.F of the two numbers.
For H.C.F, we will take the product of all the common factors in the prime factorization of the two numbers.
H.C.F
So, he can cut three inches ribbons from the
inches ribbon and five
inches ribbons from the
inches ribbon.
Hence, the greatest length he can make of smaller strips that are all equal in length is inches.
