Answer:
Inverse of the function does not exist.
Step-by-step explanation:
Inverse of a function: Inverse of a function
is a function that brings range to domain of
.
.
Given 
This function is not one-one map because 

Inverse function exists only if the function is one-one map.
Hence here inverse function does not exist.
Answer:
Step-by-step explanation:
Factor 6f3−8f2+20−15f
6f^3−8f^3−15f
=(3f−4)(2f2−5)
Answer:
(3f−4)(2f^2−5)
Find the group you want to factor, such as in the first parenthesis, you remove 3f from the whole equation, and end up with 3f-4. You take the end value, and group it with -5. You will then end up with 2f^2 -5.
Hope this Helps!
where is the figures to solve.
The actual value = 25.7 ml
The error = 15.6%
This means that the value of error = 0.156 * 25.7 = 4.0092 ml
Now, the error percentage found means that the student got the value either greater than the actual one with the value of error or less than the actual one with the value of error.
This means that the two possible readings are:
either : 25.7 + 4.0092 = 29.7092 ml
or : 25.7 - 4.0092 = 21.6908 ml
