Here is the equation:
Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
Divide both sides by -3.9 to leave the variable alone:
r is equal to 4 → r = 4
Answer:
- There is no power of 2 that is equal to 0.
- Its inverse does not have any x-intercepts.
Step-by-step explanation:
Given the function
This function can be written as:
As the rule tells s that
so
As we know that the value of x=0 at y-intercept.
For any value of , this statement is false as there is no power of 2 that is equal to 0.
Also
Lets interchange x and y in the equation to find the inverse of the function.
So, it doesn't have any x-intercepts as for any value of x, the value of can not be zero for this function.
Therefore, Its inverse does not have any x-intercepts.
