Which function has an inverse function? a. f(x)= |x+3|/5 b. f(x)= x^5-3 c. f(x)= x^4/7+27 d. f(x)= 1/x²
Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values, and , that have the same output value y
Note that the function is not a one-to-one function
When x=2
When x=8
Note that the function is not a one-to-one function
When x=1
When x=-1
Note that the function is not a one-to-one function
When x=1
When x=-1
Then the answer is the option B.
You can verify that The function is a one-to-one function and therefore its inverse is a function
(23*2)-12=x x=34
step-by-step explanation:
costs the what? what is the cost of the pants?
step-by-step explanation:
if it is $10, then the price is 14.
take 40% of the cost, and then add the cost.
40% of 10 = 4
4+10 = 14.
