What is the inverse of the function f(x)=3cube
1 answer:
Answer:
Inverse does not exist.
Step-by-step explanation:
Given is a function
We are asked to find an inverse for this function.
On analysing the function, we find that for all values of x,
y is a constant.
In other words, this is nothing but a constant function which is a horizontal line parallel to x axis.
This is not onto, because range of this funciton is only the value {3^3}
Inverse exists only for one to one and onto funcitons.
Since this function is one to one but not onto, inverse does not exist.

Answer:
x = 50
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other two sides , then
x² = 48² + 14² = 2304 + 196 = 2500 ( take the square root of both sides )
x = = 50
